I go to the Borgata at least twice a week. Mondays and Wednesdays no limit tournaments are the best games in town. If I need a break, or want to go to the boardwalk, then I head to the Trop. Thursday 10k first place game is good, and usually caps at 200 players.
Harrahs runs a deep stack tournament once a month, but their location is terrible.
Most of the poker dealers in AC play at the Hilton, very nice poker room, but limited number of games. They used to run a 10:00pm no fee $100.00 buy in tournament, not certain if they do anymore.
I won a satellite tournament @ the Hilton, for the NJ State championship in Sept. That should be a good game
Overall for poker players, I would say the Borgata has the best games in town. The Taj used too, but they have a reputation now, for years actually, as the "ghetto" poker room. I have heard many a story of players getting rolled in the bathroom near the poker room. It is right near the exit to the street, so it is easy to rob and run, half drunk poker players
Sands closed down, and in Oct they will be imploding the old building for a new casino, that is owned by the Borgata parent company. That will bring a huge poker room to the boardwalk.
Casino action: I would stick to the "Total rewards" casinos. Like Harrahs, Ceasers, showboat and Ballys. It is hard to get decent comps in AC anymore, at least compared to the good old days, but using a total rewards card, you can carryover your comps to all the casinos owned by Harrahs.
Limits: Borgata is the highest limit place in town. Most days you will be hard pressed to find BJ tables for less then $50.00 minimum. On the flip side, the Hilton has the lowest limits in town, you can usually find a $5.00 BJ table, even on a Sat night.
Check out the water show at the Pier across from Ceasers. Worth the walk.
Trumps places are a shadow of what they used to be. They are constantly "re-inventing" themselves, and IMO they have failed every time. In the early 90's, Trumps places were the best in town, but those days are long over. The Plaza, Marina and the Taj are mostly slot houses, with very little attention, or effort, given to the table games player. If slots are your thing, then Trump is the place to go

. I personally don't like slots, so I usually avoid his places.
Entertainment: Borgata. They get top notch gigs. Going there to see Areosmith in Sept
If you are under 50, the shows on the boardwalk are most likely not for you
Atlantic City always was, and still is for the most part, an old folks home with slot machines. The Borgata brought in a younger crowd, and places like the Trop and Ceasers kept up with the competition. The other casinos didn't. They still cater to the busloads of grannies from NYC and Philly, and they neglect everyone else.
Just my opinion of course!
