The integration of nature into the resort experience is what the Ritz-Carlton, Naples, is all about. There's a boardwalk through a mangrove swamp on the way to the beach, and ecotours are available. The Ritz Kids room has aquariums full of local marine life — and an environmental expert on staff.

But the beauty of this resort on Florida's Gulf coast isn't all natural. The artwork on the hotel walls is a stunning, museum-quality collection of British and American art from the 18th and 19th centuries. It's worth taking a self-guided tour of the artwork and antiques, using the brochure available from the concierge.

Then there's the spa, a 51,000-square-foot oasis of peace and calm. Meeting space includes the 10,000-square-foot Ritz-Carlton ballroom and the 3,600-square-foot Plaza ballroom.
