Epcot lounge question

Nice. I like watching fireworks from the balcony. This goes back on the list for future trips. Last trip, I tried to book the villains event in the lounge but it was full for all nights of the week I checked. That seemed odd, as I don't ever remember this lounge being busy before pandemic. Sure, the balcony would fill up right at fireworks time, but inside was always on the slow side when we visited.

I wonder if the drinks window would serve a slice of the seven layer cake? That was always a favorite!
