I had a great time the one time I attended Atlantis for the PCA in 2006. Normally, Atlantis doesn't have a poker room, but during that week, they set up poker in the ball room where the big tourney is and there's many games going all week. When you bust out, which I did in about an hour and a half on day 1
, you can head over to the cash game or play a sit and go if you'd like. They do run other smaller tourneys during the week. The cash games are all really juicy as many are drunk and just looking for a good time. Also when I went, there were many big time pros so it was fun railing them during the tourney and cash games.
As far as the actual hotel, I stayed in the Coral Tower as many other poker goers did and it was very nice. The casino is a little small, but not terrible, has the usual slots, tables. There are like 3 or 4 different beaches to go to on different sides of the hotel, with several pools and bars, plenty of options. We did do a lot of gambling that week, but did want to make sure that we got the whole experience, going to the beach, pool etc. Also, a lot of good places to eat, some of which are a little pricey. However, when you only have to worry about spending $ on gambling and drinking, it makes the trip extra nice.
Overall, the best vacation I've ever been on and I'm looking forward to going again sometime in the near future.
