Most expensive spa treatment

20-Hands Duo Massage for $4,000 Spa: Spa Grande at the Grand Wailea, A Waldfor-Astoria Resort, Maui Though the Grand Wailea’s 20-hand couple’s massage was originally a limited-time only, 20th anniversary treatment special, it’s popularity has led to it become a staple treatment worth a whopping $2,000 per person. The once-in-a-lifetime opportunity ended back in September, but started with an hour of relaxation time, followed by a 100-finger frenzy of oils and phalanges. But for those who missed the deadline, the Maui resort has no shortage of extravagant offerings, including the Kokoleka Truffle Body Cocoon & Facial ($285 minimum), Volcanic Ash Cocoon ($230 minimum), and Diamond Facial ($325 minimum).
