"His and hers: Just say ah…. Even spa skeptics can't refuse Vegas's five-star saunas, Roman baths, beautiful treatment rooms, and world renowned therapies. Hard Rock hotel’s Reliquary Spa has a mixed-sex hammam, so twosomes can steam together before heading into their joint acupuncture-inspired treatment. And the couples experience at Qua is a dream: The facilities are first rate—including Roman baths and a snow room—and you can precisely tailor the package to your partner's desires. Hand-holding is encouraged, and there is a warm room for you to relax in together before re-entering Caesars Palace."
