Another of the smaller spas in Vegas, Vdara has just 11 treatment rooms and an atmosphere that eschews the recent trend of social spa-going. There are no communal hammams or co-ed plunge pools here, just a quiet oasis in the midst of Sin City. Opt for one of the partnered product treatments, like the Red Flower Hold Life Ritual, a 90-minute detoxifying experience that involves an orange and sea salt exfoliation, honey-and-flower wrap and scalp massage ($250). For something a bit less expensive but equally indulgent, opt for the Veuve Cliquot pedicure, which comes with a flute of bubbly ($75).
