Head to the desert for some glitz and glamour. Riviera Resort & Spa, a former desert hot spot that in its heyday played host to the Rat Pack and other Hollywood elite, has undergone a two-year $70 million upgrade to the resort’s amenities and design, creating an ultrachic contemporary tribute to 1960s Hollywood. The new décor includes vibrant colors, Andy Warhol-inspired artwork, sleek lines, French and English retro-style furniture, and a futuristic lighting scheme. Outdoor areas have been replenished with fresh landscaping and comfy open-air living spaces complete with firepits. New ultra-hip bars like the lobby’s Star-Lite Lounge and poolside Bikini Bar offer great atmosphere and a chance to mingle. The redesigned SpaTerre offers a calming and exotic theme, with bamboo, crackled glass, chocolate brown accents, and the coed Buddha lounge filled with replicas of tropical palms.
