I'm getting married next weekend and I wanted to find a aplace we could go to after the reception. I'd rather not have anyone pay a cover. This website has everything and it also listed the clubs and lounges that do not have covers or minimum drink requirements. Since I don't know when this list was made it's probably a good idea to call the venue of your choice to make sure. Since the private home we rented is 3 miles from Mandalay Bay we will probably do EyeCandy. I hope you find this information helpful. I'm not sure if you want to add this to your mega list

Re: As promised I found a list for "free" lounges and clubs
Married in Vegas - June 2011
Every time we go back we try to pop in there for at least a drink but I don't think we've made it down there the last 2 times we were in Vegas.
