The Pool at JW Marriott Marco Island Beach Resort

"A $187-million face-lift in 2007 added a 24,000-square-foot spa, poolside cabanas, and a new clubhouse for the hotel's golf course, the Rookery at Marco (which is seven miles away on the mainland)"

"Kids love the zero-entry pool with a slide and water features, and adults station themselves at the beautifully landscaped one next door"

"The handful of one- and two-bedroom beachfront villas are far from the main building and provide more privacy and easier beach and pool access"
