Sheraton Grande Tokyo Bay Family Rooms: Which Sleeps Four

This guide to Sheraton Grande Tokyo Bay family rooms answers one question: which room actually has four real beds, not a rollaway pushed into a corner. Marriott's own room guide for the hotel (checked August 2026) confirms two different four-bed layouts in the same 36 or 40 sqm footprint: the Standard Room and Ocean Dream Room, built with two 137–140cm beds plus two 97cm single beds, and the Treasures Room, built with two 120cm beds plus a two-tier bunk bed. The cheapest of those is the Standard Room. The hotel's own lowest listed rate for two guests was ¥32,580 a night in a September 2026 check, before the cost of the extra beds is added. That answer changes if a fifth guest is travelling — the 54 sqm Family Premium Room comes with five fixed beds built in, for up to five guests. I spent the night of 29 August 2026 in that room with three others, and the two numbers that matter are not in the room guide: the app listed it at ¥78,375 for that night and the four-to-six-bed Treasures Room at ¥76,475 when I checked three days out, on 26 August 2026 — roughly two and a half times the quiet-season from-price quoted above, because the last weekend of the Japanese school holidays is the single worst date to need four beds at Maihama.

The room types that take four

Sheraton Grande Tokyo Bay is one of Tokyo Disney Resort's six Official Hotels, and its room lineup is built around a small number of base categories rather than a long menu of named suites. Marriott's own room guide for the hotel (checked August 2026) lists the Standard Room (3rd–5th floor) and Ocean Dream Room (6th–7th floor) as sharing the same bedding rule: the first two beds are 140cm or 137cm doubles, and the hotel adds two 97cm single extra beds to reach the four-bed configuration. That is where one "four real beds" answer comes from — two doubles plus two singles, rather than a sofa bed or a rollaway pushed into a corner.

There is a second confirmed four-bed answer, on the 8th floor: the Treasures Room, in the same 36 or 40 sqm footprint, is built with two 120cm beds plus a two-tier bunk bed rather than two loose singles — the same room guide lists 5-bed and 6-bed versions of it for larger groups by adding a 97cm bed alongside the bunk. It suits a family that wants the extra sleepers built into a kids' bunk rather than a second adult-sized bed. The Family Premium Room is a different tier again: 54 sqm, positioned on the corner of each floor, permanently equipped with five beds for up to five guests — useful for a fifth traveller, but not a room that comes at the Standard Room's price point, and neither the floor nor the exact bed layout can be chosen at booking. A Park Wing Room exists as well; it is marketed for guests travelling with a dog and is not part of the four-bed comparison here.

What the five-bed room is actually like

I booked a standard floor for the night of 29 August 2026 and was moved to the Family Premium Room at check-in, as a Marriott Bonvoy Platinum upgrade. That is worth stating plainly, because it is the part a reader cannot plan around: the upgrade is a benefit the hotel gives when it has the inventory, not something the booking guarantees. What the booking did guarantee was the price — one room, four guests, on a 50,000-point Free Night Award plus a 13,000-point top-up.

The room is laid out as two spaces rather than one. The main area holds the larger beds, a table with chairs and a sofa, and opens onto a balcony through a full-height sliding door. Behind it, an alcove holds the remaining beds side by side, and a curtain pulls across to close that alcove off from the rest of the room. For a family whose children go to bed before the adults do, that curtain is the feature — the difference between everyone sitting in the dark at 21:00 and the adults keeping a lit room and a balcony. I did not measure the beds; the centimetre figures above are the hotel's.

Ours was on the park side, and Cinderella Castle is visible from the window in daylight, small but unmistakable. Fireworks are a different claim and one stay does not establish it — the side faces the right way, but whether a show runs on your night is a separate question.

What the hotel gives you as an Official Hotel

Official Hotel status brings two things worth planning around. Bags can be sent ahead from the station to the hotel on arrival day free of charge if they are handed in between 08:00 and 15:00, so a family arriving by train is not hauling suitcases across the resort — the deadlines and the exact counter are in our guide to baggage delivery at Tokyo Disney. Guests can also buy date-specific park tickets during their stay, a process worth reconfirming on the resort's own site close to travel.

What Official Hotels do not get is Happy Entry, the early-park-access benefit. That is a tier rule, not a hotel-by-hotel one: Official Hotels sit outside the Disney Hotels tier, so no version of it is available here, and a family choosing this hotel for its four-bed room should not expect an early-entry voucher at check-in. Even inside the Disney Hotels tier the benefit is narrower than a hotel list suggests — limited by property, by date, and to the non-check-in days of a stay — which our guide to early entry by hotel works through against the resort's current guest-benefits page (checked August 2026).

Getting to the parks

The hotel connects to the Disney Resort Line monorail at Bayside Station, either on foot (a 5-min walk) or aboard the complimentary Disney Resort Cruiser shuttle (about 3 minutes). From Bayside Station, the monorail runs the loop that serves both Tokyo Disneyland Station and Tokyo DisneySea Station, and the same line connects back to Resort Gateway Station, next to JR Maihama Station, for anyone continuing on to central Tokyo. None of this requires transferring bags or strollers between separate stations — the walk and the shuttle both start at the hotel's own entrance.

The garden pool is summer only, and it is not free

The notice board beside the Garden Pool gave the 2026 season as 18 July to 30 September — a shorter window than the June start that circulates in English write-ups (read on site, 30 August 2026). Outside those dates it is closed regardless of weather.

The surprise for a family budget is that it is a paid, reservation-only facility even for hotel guests: ¥3,000 an adult and ¥1,500 a child aged 4 to 12, sold in five fixed two-hour sessions between 08:00 and 18:00, with a Night Pool from 18:00 to 21:00 at a flat ¥4,000. Lockers are ¥1,100. Two adults and two children come to ¥9,000 before a locker, on top of the room — an attraction with a ticket price, not a hotel amenity. The free pool is the separate indoor one, open year-round; the recreation floor's price list states that the indoor pool and the gym are free for hotel guests, then adds the line that catches people out — a locker there is charged at the public-bath rate of ¥1,100 for an adult and ¥750 for a child (read on site, 30 August 2026).

Four beds, three hotels, one date

All three official hotels below keep at least one room with four real beds within a 6-min walk or a shorter shuttle ride of Bayside Station (checked August 2026). The harder filter for a family of four is not which hotel, but which room category inside it — and, on a peak date, whether that category is still on sale at all.

• Tickets and day trips — Klook covers Tokyo Disneyland and DisneySea tickets, teamLab, and day trips out of Tokyo; booking ahead skips the ticket-window line.

FAQ: Sheraton Grande Tokyo Bay with kids

Which room sleeps four in real beds, not an extra bed?

Two room types do, per Marriott's room guide for the hotel (checked August 2026): the Standard Room and Ocean Dream Room, at 36 or 40 sqm, pair two 137–140cm beds with two 97cm single extra beds, and the Treasures Room, on the 8th floor in the same footprint, pairs two 120cm beds with a two-tier bunk bed. The cheapest of the two is the Standard Room. The hotel's own lowest listed rate for two guests was ¥32,580 a night in a September 2026 check, before extra-bed charges.

Is Sheraton Grande Tokyo Bay a Disney Hotel or an Official Hotel, and does that matter?

It is an Official Hotel, one of six in that tier. That status brings the Baggage Delivery Service (free, 08:00 to 15:00, at the Hotel Service Counter on the ground floor of the Welcome Center beside Maihama Station) and on-property ticket purchase, but it does not bring Happy Entry — which even inside the Disney Hotels tier is limited by hotel, by date, and to the non-check-in days of a stay.

How long does it take to reach the parks?

Bayside Station, on the Disney Resort Line monorail, is a 5-min walk from the hotel or about 3 minutes on the free shuttle. From there the monorail loop reaches both Tokyo Disneyland Station and Tokyo DisneySea Station.

Can I count on a room upgrade with Marriott elite status?

No. I was moved from a standard floor to the five-bed Family Premium Room at check-in on 29 August 2026 as a Platinum benefit, but that depends on what the hotel has unsold that afternoon, and the last weekend of the school holidays is not a night to expect it. Book the bed count you actually need.

Is the Garden Pool open in winter?

No. The notice at the pool gave the 2026 season as 18 July to 30 September (read on site, 30 August 2026), and it is closed the rest of the year. The indoor pool on the recreation floor runs year-round and is free for hotel guests, though a locker there costs the public-bath fee of ¥1,100 for an adult.

Prices in this article are the hotels' lowest listed rates for two guests in one room for one night, room only, checked in September 2026 — not a guaranteed rate for any specific date. The lowest-priced four-bed room is usually the first to sell out, so read the from-price as a rate that exists on the calendar rather than one available close to a trip. Tokyo Disney Resort's hotel tiers, benefits and seasonal hours change from year to year; the tier and Happy Entry details above were checked against the resort's official site in August 2026 and should be reconfirmed close to travel.
