Family friendly hotel + 50,000 sq ft water park = License to print money.
Well, judging from the amount of kids and families we met during our recent visit to the Great Wolf Lodge Resort in Grand Mound, Washington, it certainly must be. The concept is simple; build an awesome water park packed with slides, rides, wave and kiddie pools and hot tubs, inside a hotel resort complex with restaurants, bars, cafes, a spa, arcade, Starbucks, and gift shops, and presto, you've got family theme-park travel success.
