Fodor's Expert Review Big Horn Resort, Ascend Hotel Collection

If you've brought the kids along, this is the choice, hands down, for one clear reason: a 35,000-square-foot indoor water park ($10 per person per day for in-house guests) with two three-story slides, four minislides, a wave pool, and a 20-person hot tub for the older set. If that's not enough, there's a games arcade. On the other hand, those who find swimsuited, barefoot kids racing around annoying rather than cute should choose another property.
