Neither, with boys I'd go to ASsports. Its getting refurb to be done the beginning of 2008. I don't like that Pop and Movies have made so many of their rooms preferred which means you will be paying $12 more a night. I don't mind paying that if I am going to be in the bldg closest to the pool, lobby, and food court.

Bldg 10 is great, close to the pool, lobby, and food court with a back way to get to the buses without going through the lobby.
good luck with decision.
