My fiancee' goes all the time. It's $20.00 a session where she goes. It lasts about a week. It lasts longer on your body, but not on the face. Also if you don't use lotion every day, it cracks. BUT it looks GREAT. Depending on the level you get done (they have darkness levels 1-10), you look as if you spend a summer in the tropics, or a few days at the beach.
When you get it done, wear loose fitting clothing. If you wear anything even remotely snug, it will rub off the tan. Do NOT go near water for at least 8 hours. The tanner gets darker and darked up to an 8 hour period. It is best to wait and shower the next day. You may look extremely dark the first day, because of the tanner AND bronzer they use in the mix, but when you wash the next day, it's the best tan you've ever gotten.
Good luck, and hope you like it!
Ps. A lot of the places know how to 'etch' your abs, etc, so ask about that when you call, if you want to look a lil more defined.
