Weddingbee boards

My sister is getting married in June in Vegas and I am trying to figure out a good place to have a bachelorette get together.  She is adament that she does not want to do something that involves strippers or too much of a "club" feel because it will be a mix of older and younger ladies, although everyone will be over 21.  I haven't been to Vegas since I was about ten years old, so obviously I am not too familiar with good bars, etc. there.  Does anyone have any recommendations on fun, somewhat inexpensive things to do or funs bars where everyone could go to talk and have drinks? 

My group of girls who will range from 17-67 are going here http://www.rainbowfeatherco.com/  for  a girls event.  Ive arranged that we can make our own feather boas- and have a photo shoot.  Then the next day we are doing a spa day- at the Golden Nugget.    Just a couple of thoughts.
