I know it is pricey and may not be the most convenient - but you will be blown away by the spa at the Grand Wailea. Combine the day with a visit to Makena Beach or the shops at Wailea. Go an hour early to the spa to enjoy the included Terme treatment with the loofah scrub. Have a wonderful massage - and enjoy the spa facility after your service as well.
I am at the point that I don't even bother getting a massage while out of town anymore - feeling like i have thrown money away after getting so-so massages - except here. I have ALWAYS been happy with the therapists at the Grand Wailea.
And they take SpaFinder gift certificates - that can save you 20% right off the tip - buy them at Costco - you get $100 for $80 there.
