I will be visiting Vegas in a few weeks and have narrowed my list down to three providers.  Can those of you more knowledgable of the local scene give me your thoughts on the following ladies?  I am looking for a two hour appointment.  Also, if I have left off the obvious please advise.

Elizabeth Layne
Mia
Nikki Avalon

It does not seem that I could go wrong with any of them but would appreciate any insight you could give me.  Thanks.
