DOES GENERAL ADMISSION MEAN A 3 HR WAIT ON LINE AT THIS VENUE? ANYONE?

Does anyone have experience going to a GA show at a venue this size - this place has about 2,000 seats. Will it be hours on line to get in? Not sure if I want to wait for hours outside in the freezing cold - NYC always seems so much colder than the suburbs! Of course, I guess one could always go late and not wait, but end up in the back.

I may give up my tickets since I am going to Toms River and as of now I am in Sec 117, just a few rows off the front corner of the stage for that show. Though I may trade up for floor tickets if any close ones are available - have only seen 13 row or so lately.

THANKS FOR YOUR HELP!
