Ok, I'm not a big vegas club maven, but I've danced my fair share of nights away. I really liked Marquis. Maybe because as a hotel guest, we got in free? Maybe because it's got a great indoor AND outdoor dance area. We found a little area around the corner to the left when you go outside that has little daybeds and tables. We just hung around for a few minutes and claimed a few.
Yes, well drinks are $12 bucks...but we tipped the outdoor bartender well and he made sure our drinks were worth it all night.
Ladies - if your feet are killing you because you thought somehow you could live all night in those insane stiettos, never fear, they sell flip flops in the restroom for $10.
OR just stay at the best hotel ever, take your shoes off when you leave the club and take the old elevator upstairs:-)
