With such a late opening for Epcot, I would think that ropedrop is not as advantageous there... but I’m just speculating.
I do, however, know that I love Topolino’s (dinner & breakfast- they were both superb!)!! So, I would definitely keep the ADR & keep trying to snag an earlier time (your best chance to catch one may be the night before as people are canceling), or just show up early & hope to be seated quickly. Good luck & enjoy!
