Can a family with 3 children stay in one room?
With two adults and three children you are five people. Whether one room is enough depends on two numbers the hotel publishes: the room’s maximum guests and the age up to which a child can share a bed without being counted (here: preschool age).
Luxury Family Room:3 to 5 guests; 5 sleeping places (4 beds (120 x 203 cm) + 1 sofa bed (90 x 195 cm)).
Japanese Suite:Not confirmed; sleeping places Not confirmed.
Deluxe Select Connecting Room:3-4 guests (two connected rooms, 71 sqm in total); sleeping places Not confirmed.
Plaza Deluxe (South Tower) Triple:3-4 guests; 4 sleeping places (3 beds 110 x 203 cm (Hollywood twin + 1) + extra bed 110 x 188 cm).
1 of the room types listed here take 5 or more guests in one booking. If your children are older than the bed-sharing age, count each of them as a guest and make sure the room has a sleeping place for each.

* Sold as a pair: Our reading, not the hotel’s wording: when two connecting or adjoining rooms are sold as their own room type, booking that room type should get you both rooms together, unlike a “connecting request”. Most hotel pages do not use the word “guaranteed”, so confirm with the hotel if it matters.
We have not stayed at this hotel. This page only summarises what the hotel publishes; the hotel’s own page and your booking confirmation take priority. “Not confirmed” means the pages we checked do not say.
