We've stayed at Sports twice in the past three months, and I can't imagine paying $10 extra for a preferred room. The resort is not spread out, so walks from regular rooms are not far. In addition, if there is a big group of young people there, there's a good chance they will be in the main pool making noise late at night. I'm pretty flexible, but I would have been pretty unhappy Dec. 22 if I had been paying for one of the "preferred" rooms. I walked to the laundry at about 11 p.m., and there were at least 100 or so teen boys in the pool, most of them yelling. My DS says that's pretty much what it looked and sounded like when he was there for grad, too.
The resort is fine, BTW. The rooms have been redone and are nicer now. A bit on the small side, of course.
