Yeah, I understand that but for Marriott hotels in Osaka and Tokyo (only cities I checked) they do not have any rooms that allow 3 adults. If you go and search for 3 it just says no rooms available.

When we took my father in law a few years ago he just got his own room but we're traveling with 18 year old niece so don't want to do that and luckily it's only 1 night we need a hotel. At least the Sheraton allows for it so we booked there. Does anyone know if they will charge lounge access for 3rd guest? Any idea the cost? Thanks.
