Fodor's Expert Review Hotel Riu Palace Tres Islas

You can step right onto Grandes Playas, one of the best beaches on the island, from this hotel, which resembles a cruise ship with its six stories and curved white facade. Inside, things are decidedly dowdier—the rooms are spacious, but the beige-and-red accents and heavy curtains are odd choices. Rooms face either the ocean or white dunes.
