extra workshop reservations?!

Hi! It’s only my second ever convention, my first being NYCC last October. (I’m from NY, so it’s also my first time on the west coast) Unfortunately I was unable to get any reservations for all the workshops I was looking forward to :(( I waited in all the queues when the reservations were released but no luck. I know at NYCC there was like an area/line you could wait on for extra spots on panels and stuff so I was wondering if they had something similar for workshops. Just curious, thank you!
