Hi! Just got back today from our trip. We did the EMH evening hours at Epcot on Thursday evening.
We didn't go into the World Showcase, we had done that the night before. We were able to walk onto Mission Space, but had to Fastpass Test Track. Even then, the wait was only 25 minutes. We went on Imagination and Spaceship Earth, both walk ons but I don't know if there is ever a wait for those two attractions these days.
Soarin wasn't open yet, and the Land hadn't reopened yet.
I'm pretty sure we did everything there was to do in Future World. It was a good time, though a little cold. The parks were pretty empty and we had a great time.
