Questions about a Mystic Tan

I need some help.

You see, Sarah's wedding is next weekend and I'm a bridesmaid.
(Nah... thats not the problem).

The problem is that the dresses are these cute strapless pink things and I'm P.A.L.E.

I have a few options to help me fix this but I don't really like most of them.

I've done the "real" tanning bed thing a lot in my life and I really don't want to go back to that.

I've done the tanning lotion thing-which I like- but it doesn't work so well for the whole body, June Wedding experience. 

One option that I think I like is getting a Mystic Tan. 

Have ya'll ever gotten a Mystic Tan before? 

I have some questions:

1. Will it turn my ankles and elbows orange?

2. How long does it last?

3. If the wedding is June 12 (one week from Saturday) when should I do it?

Any other advice you have will be greatly appreciated!
