How early should i get there to a jesse mccartney concert (general admission) to assure i get good seats?

the concert is at the palladium ballroom which i think is pretty small and i really want to get close, but i don't want to be so early that i'm waiting for hours.How early should i get there to a jesse mccartney concert (general admission) to assure i get good seats?
well like all other general admission concerts, there will be a line to get in because the earlier you get there, the best seats you will get. um i went to his concert last year in nyc and it was general admission and i got there 2 and a half hours early and got pretty good seats (even though it was standing room) so if you want to be like REALLY close, be there at least 3-4 hours early. i know it sounds like alot but it will be worth it. if you dont wana wait that long, call the place up and ask about it. theyll wana help a paying customer.
