I've been going to the Flamingo Party for years. It's all the food and drinks that you can handle. There's wall to wall with big screens to watch the game. Booth outside to place for your prop bets. It's not a bad party.  
But the guys want to branch out and try another hotel. If we don't have access to other hotels due to VIP status, we're not worried, we'll get in, we "know" people....lol
So which hotel can we crash??? We promise, you won't know we're there....yeah,right.

Hey buddy
I've been going to SB party's at casinos for over 10 years. Right now Aria has the best. They have couches to sit in and always have hot girls walking around in hot little referee outfits. The food is great too. Wynn and Cosmo put on a good show but I'm not a huge fan of the table seating. It's nice to sit at a round table with 10 other people but the seats get a little uncomfortable around the 4th quarter. Good luck getting in!

Last year I went to a great Super Bowl party at the Wynn.  Lots of screens and great food with a great crowd.  I'll definitely do it again.
