713 Music Hall Seating

I'm trying to buy tickets to see NFG, All American rejects, & Motion City Soundtrack at 713 Music Hall. The 2nd floor seating tickets are around $50 & GA Standing only are $70. For 2 tickets & all the fees Live National adds, it's going to be close to $200 for GA. Does anyone know if I'll be able to sneak into the GA section if I buy seated tickets for 2nd floor or are they strict? I hate sitting during shows but I hate the ridiculous fees Live Nation tacks on more😭
