Formerly the Mondrian Scottsdale, and a James hotel before that, the Saguaro remains trendy in the new hands of the San Francisco-based Joie de Vivre company. The 194-room hotel, which opened in November 2011, was given a kicky overhaul by Stamberg Aferiat + Associates, drenching seemingly every available surface in a spectrum of bright paint colors inspired by Arizona wildflowers. Does your idea of pool bliss involve a party or a relaxing day in the shade? The Saguaro has the ultimate pool and aplenty of breezy lounge seats to park your towel.
