I usually play at the Tropicana, not a bad place to play w/ some decent poker games
The Borgata is also fun, with actually attractive waitresses and a younger crowd.
The Taj is the Taj. You'll have dirt under your fingernails for days after playing there and the chips are gonna stick together, but the action is very loose and wild if you can handle it.
It can be pretty expensive to stay at the casinos in Winter around the holidays. I would look for some stand alone hotel room or find a place in one of the surrounding towns like Abescon. If you don't mind paying for the cab and being a little farther away its a good deal...you probably wont spend much time in the room anyway.
