To Cleanse My Mind, For Reals

I'm off to Chiva-Som Spa in Thailand.
I'm staying in the Thai Pavillion for the 5-Night Inclusive Package.
Airfare costs me about $3,000.
Which leaves me about $100 in pocket change for whatever. I don't plan on spending it on much more than cab fare and maybe wine on the plane, because this get-away is just going to be me, my thoughts, and a whoooooole lot of pampering!
A very special use of $7,000, yes?
