Grand Hyatt Kaua’i Resort and Spa: Best Hotel Swimming Pools in the U.S.

That honor goes to hotels in Hawaii, Vegas, and Walt Disney World-- according to the Fodor's Forums. Hawaii may boast incredible beaches, but the pool attractions are just as jaw-dropping. Case in point: the five acres of meandering lagoons and pools at the Grand Hyatt Kaua'i Resort and Spa, set within beautifully landscaped gardens. Kids go gaga over the water slides, waterfalls, whirlpools, and neat, 1-acre free-form pool. (They'll also love the koi fish feeding and hula lessons at Camp Hyatt.) You can even kayak in the salt-water lagoon. Nestled on the south side of Kaua'i, Hawaii's Garden Isle, the oceanfront resort also has a full tennis complex and Anara spa. You can play a round of gold at the Poipu Bay Golf Crouse, home of the PGA Grand Slam, right next door.
