I think your best bet would be to rent a vacation home. You can easily get a 4 bedroom place. We have stayed offsite in a town home two years ago and a 4 bedroom house last year and both experiences were wonderful. Having extra room is fantastic. You will know exactly what everyone in your party is up to because you are in the same house. When we have stayed in a hotel and there are several rooms of people, I have always been paranoid to knock on someone else's door because I was afraid they were sleeping. In a house, it is easy to know if someone is resting in their bedroom and those of us who are awake, can visit in the kitchen, living room or by the pool. There are plenty of rental home sites. I like vrbo.com.
Good luck.
