borgata as a first timer

I will be going to the Borgata this weekend in Atlantic City as I am about to turn 21 and can legally play in the casino.

In your opinion how do you think the field for the $120 morning tournament will be? I will post a link with the structure but I am just trying to decide if I should take a shot or if it will be well past my skill level in which case I would stick to 1-2 cash games.

To give a background on my skill level I am rather new to the game still. I have read multiple books at had a runitonce subscription for a few months while I was playing online (although this probably applies more to the online poker world). I managed to take a small $35 deposit on Ignition to about $3000 over the course of a few months (mainly from one tournament win, $10 buy in around 1700 runners, something like $2000 for first). After that I was on a cash game grind of various different limits to increase my bankroll until I eventually cashed out.

Any tips or recommendations for a first timer would be great!
