I did not stay at this hotel, I actually stayed next door at the New York New York. But I did play at the casino in Monte Carlo, more specifically the poker room. I found the environment of the poker room to be very friendly and not pretentious in the slightest, both the players and the casino staff. The poker room "host" (the guy running the room) was very nice in explaining the different games they had going on. They probably have other games, but I played in a $50 no limit texas holdem tournament, which they run with only 8 to 10 people, so the game doesn't last forever. They also have a $1/$2 no limit texas holdem game for buyin of $100 min and $200 max, where you can join and leave the game at any time. The waitress did a good job of keeping our drinks coming, although there was one lull where she noticeably disappeared for a while. All in all, this was a friendly, non-intimidating, unpretentious environment.
This is in contrast to the poker room at either Bellagio or Caesar's, I wish I could remember which one it was. But at that poker room, the poker host was very pretentious. We had asked him what kind of games they had running, buy in amounts, blind levels, etc., and his response back to us was filled with attitude and pretentiousness. And very cryptic. He definitely had an attitude. And seeing as how we don't play poker in Vegas EVERY SINGLE DAY we weren't quite sure of what was going on, hence, our questions. We do play in quite a few home cash games so it's not like we don't know how to play the game. We just didn't know what the different games were in that particular casino. Snobs. But anyways, I guess what I was getting at was that the poker room at Monte Carlo was very unpretentious and very welcoming, in contrast.
Pros: friendly and welcoming poker room w/o attitude
