I just did Epcot eve emh last week so I can tell you how it was that particular night. No FP+ during emh.
We skipped Illuminations to go watch Capt. Eo and ride Figment (both no waits). TT was 30 min wait just before Illum. and Soarin was still 45 min which was why we opted to wait.
We got out of the Imagination pavillion around 9:15ish just as Illum was finishing, wait at TT was listed as 20 min so we zipped over there, it might have only been 15, not bad at all. We were going to ride again but it had moved up to 40 min when we came out as people streamed in from Illum. Headed to MS but the orange side was down, not good. That funneled even more people to TT and it ballooned to 50 min. Soarin was around 40 at that point.
We sat on a bench to eat our desserts we had earlier purchased in the candy shop in Germany. Luckily the orange side of MS came back up with 10 min. wait so some went to ride that. By 10:30 TT was still 50 min, but Soarin dropped to 15 min! My group opted to ride Spaceship Earth and shop, no wait at Spaceship Earth. Wait times for the stuff in the Seas was 15 min so not bad.
We thought it was worth while, nice to stroll back through the empty countries on our was to the Dolphin.
