For an airport hotel, the Doubletree is surprisingly serene and stylish. Moorish arches, potted plants, stone fountains, and colorful tiles create a Mediterranean mood in the public areas. Intricate wrought-iron elevators descend from the guest floors to the lushly landscaped pool patio, eliminating the need to tramp through the lobby in a swimsuit. Guest rooms are equally appealing, many with brick walls, wood-beamed ceilings, and draped French doors. And because this hotel gets a large business clientele from Mexico, most of the staff is bilingual. The hotel offers free shuttles to the airport and other destinations within 2 miles.
