From my one trip to Vegas I have one suggestion. Stay away from Margaritaville. Worst restaurant I have ever been in, in pretty much every way imaginable.
I would have imagined that the biggest problem for you in Vegas is that there isn't enough lawn for you to yell at people to keep off of.
Wynn and Encore are the only ones worth going to. I hear the M-Resort Buffett is pretty good as well. Aside from Sushi Koma (http://www.yelp.com/biz/sushi-koma-las-vegas) and Goyeman (http://www.yelp.com/biz/sushi-house-goyemon-las-vegas) Long ass waits but that shit is the bomb.
I'm going to Vegas this month, I'll take pics of the three comped buffets I'll be having to put el prez's statement above to the test
Excalibur three nights comped through credit card points, one night Monte Carlo comped through myvegas. two Jabbawockeez tickets comped through myvegas, two buffets to Mandalay bay, Luxor and Monte Carlo comped through myvegas. Then the wife bought tickets to Britney spears so we will be seeing her too. Also got a bogo coupon from myvegas for the sugar factory lollipop passion fruit cocktail
Look for discount tickets at those booths to see Fantasy at the Luxor. The gf and I really enjoyed it.
I've heard great things about it. I think we are going again in august for my mother in laws bday. They wanted to go see it then.
Haha nah they are cool about that stuff. She's turning 50 and likes to let loose and have a good time.
