Oh yeah MGM Grand has a great buffet... and you're right on the strip to boot.. For eats you also got the famous Brazilian buffet where they wheel sticks of meat to your table..
Be sure to check out Cirque du Soleil's tribute to the Beattles - LOVE. Also, among true Vegas shows is the Jubilee, which has the same show, a la topless!! There's also the wax museum and an awesome aquarium that will blow your mind.
A plethora of clubs but my favourites were PURE and Luxxor. PURE's in Ceasar's Palace so it would be walking distance to you. Oh the girlies!!
I'm not a big gambler, but I like the craps tables (5-10$) cause they offer lots of play time and I don't blow the bank. The potential for a nice payout is there too.
Be careful with the dollar pina coladas though... They're chalk full of something, but it ain't alcohol!
Oh and if you go on a lude trip, don't steal Mike Tyson's tiger!!
I'm going for my bachelor party at the end of May (getting hitched in June) and I plan on getting it all out of my system before the big day..
Have fun!!
cheers
