If you're a local, check out their spa's slow day specials (most often a Tuesday, Wednesday or Thursday). It's a nice little spa in a great location and the staff was pretty good too!. It doesn't hurt that Trader Vic's is so close by and has tropical happy hour specials for afterwards :)!. Great Staycation location!
Here's a sample of the newsletter spa specials:
