We could ask you lots of questions like how old the kids are, etc. and we could speculate this or that. The only way to know for sure is to ask when you make the ressies. Seems that they will actually take a ressie for 5 in a 1 br. However, I can't say that from personal experience and I don't know if they will in all circumstances. If you are completely up front with the CM when making the ressie and they know all the particulars of who is in the party and they take the ressie I don't see any 'rationalization' going on. Now if you tell them you have 5 and they say you won't fit in a 1 br I guess you have a decision to make. That is where it gets fun.............
