I go to the Palm Beach Tan on Wigwam and Pecos only. The location is clean and the girls are friendly. The manager, though, Denise (I think) is AWFUL. She will lie through her teeth to sell you a product and will get all snippy with you if you don't want to buy anything. It's extremely annoying and I actually almost stopped going completely because I hated having to deal with her. But that's just one person.. everyone else is very nice and helpful.
The only other problem I've had is their Mystic Tan machine seems to be consistently broken. I can't even count how many times I've driven all the way down there to be told I needed to go to another location because the machine is broken. And a lot of times when it's working it gets stuck and sprays unevenly.
But if you don't Mystic Tan and don't mind pushy managers.. Palm Beach Tan is a great place with competitive prices.
