As for the "somewhat limited" list, do you remember any attractions that were or were not covered by the multi-experience pass?We were there this past weekend - @scrappinginontario's advice about booking Genie+ for rides that were down was a huge tip.
Space Mountain was down in the afternoon on Friday, but they were still issuing near-immediate LL return times for it. I would grab a LL return time and it would quickly convert to an any-attraction (it was a somewhat limited list), any-time return time.
The key here was that it also opened the booking window again (even without having used the return time yet), so I booked another one. We were able to do this 3x while Space Mountain was down and use that to stack back-to-back LL that we used on other attractions.
Thanks, @scrappinginontario!
I would expect the ILL attractions (Tron and Seven Dwarfs) to not accept the MEP, but would expect all or most of the other Genie+ rides would accept that MEP since Space is one of the more popular Genie+ selections at MK. But I haven't had an MEP at MK since the Fastpass+ days, so just don't know how it works now. I've seen lists of MEP tiers at Disneyland in California, but not for Disneyworld in Florida. I think it could be useful information to know before visiting.
