Disney for graduation??

[Travel Guru]

My now 16yr old and her friends want to head to Disney for a week vacation after graduating high school (2010). They're very serious about it and I don't have a problem with them taking a trip on their own since they're a really good group of girls...I'd rather they take the trip to Disney than the trip to Costa Rica that they originally wanted :crazy1: Here's my question...Is Disney going to allow a group of 17 & 18yr olds to book a room?? Is 18 the magic age for booking a room as an adult or is it 21 or older?? Plus, has anyone had any experience with their kids doing this?? My DD has taken over the role of planner/organizer since she's been there the most and I think she likes the idea of doing the planning :yes: (She's making me proud:D)
