Spa Mandalay is beyond perfection. I managed to book a last minute 45 minute full body massage and despite the $115 price tag, it was well worth it. Not only did I get the massage, I was able to spend all day in their spa (which is beautiful by the way). The staff are by no means stuck up or pretentious, but offer you the up most respect and wonderful customer service skills. They offer light refreshments inside as well, and they live up the Mandalay Bay's reputation. By far the best spa experience I have ever taken advantage of and even if you don't go in for services, paying the $25 day spa fee to enjoy the gym and whirlpools is definitely worth the expense.
