i was just there about three month ago with the wife. Take note:
1) When in the casinos like Mirage, Bellagio, or Caesars Palace. Observed the people and look for the old farts with young bimbos. Two things should come to mind; gold digger wife or high price escort.
2) Don't be surprise to see 20-30 people along one part of the strips, smacking these trading cards that advertising "hookers". And they will be wearing shirts saying "Girl at your room in 20 mins".
3) most casinos you will get free drinks while playing. Watch your self, that is a way they get you drunk so you can gamble more of your money.
4) you and your wife are staying at, oh lets say Treasure Island, and you want to go to Bellagio. Take a cab!!!! Event though you see the building, believe me, you will walk for a while to get there.
