well leaving on tuesday 08/05 for 5 days in Vegas. We are trying to find the best Grand Canyon tour options. Group of 10 would prefer just us and alcohol is a must!! I was also curious if anyone has done the high roller open bar>??? we got a group that can put down a 6 pack or 3 or 4 cocktails in 30 minutes just curious if the drinks are limited or if it is truly an open bar for the 30 minute ride just figure for 24.95 gotta be a catch.
