In the front of my mind is Oriental Spa and Tropical Oasis, neither of which I've been to. Places closer to me have either lost their luster or closed down and I'm looking at these as potential replacements.
Up and Down the Perrin-Beitel/Nacogdoches corridor there's multiple spas that can be counted on for whatever you're up for. 8 SPA, KK, W, A+. Many hobbyists have enjoyed visits to them all.
