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: 12 and under, using existing bedding).

Japanese Suite: Up to 6 guests on futons; sleeping places Not confirmed.
Premier Suite (Twin): Not confirmed; sleeping places Not confirmed.
Premier Room (Triple): Not confirmed; 3 sleeping places (Triple beds (Premier Room is offered as King, Twin or Triple; on the Deluxe page 'triple' is defined as twin beds + 1 extra bed)).

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.
