I've always found that asking for "what you want" is preferable to asking for "where you want". If the few buildings you name are not available, the person placing you may have no idea what your "second choices" would be.
In your case, I would ask to be "as close to the Hospitality House as possible." That gives the person placing you the ability to meet your needs as best they can. Most of the resort is within easy walking distance for teenagers in even reasonably good health. It's spread out, but it's not that spread out. Even the very farthest points are a bit under 3/4 of a mile, following the sidewalks. No more than 15 minutes by foot, and probably less.
The only time I made such a request (we usually have a car, but didn't that trip) I ended up in 27. Right next to the Peninsular Road stop, and very convenient. It was an accessible room, so the shower got a little sloppy, but that was a fair compromise for our needs that particular trip.
