I think it is worth it. Before I retired, I could attend only on Saturday. I would quickly go through the member halls first, looking for Atlas and Weaver boxes. Those were easy to spot in the sea of Lionel and K-Line normally in those halls.
I would then go to the dealer halls where the displays would stay up until close to closing. The big boys didn't take their stuff down until after closing. Many times, because I rarely found anything I wanted in the member halls, I just stayed in the dealer halls. That was worth the ticket price to me.
