Girls who are going/went to vegas for bachelorette

We are going Labor Day weekend for 4 nights. Can you recommend fun things for us to do. So far we have tix to see Thunder Down Under and reservations for dinner at Tao.

How much stuff are you having pre-planned? What bars are fun and would you recommend?

Also, we dont have to wait on line for hours to get in. Do you think that we will get in when they see we are a bachelorette party?
