Based on your ticker, it looks like Fantasmic! is at 9 (with an 8:30 park closing). I would want to be back in the park about an hour before the show, figure an hour to get to and from YC/BC (if you factor in taking the boat and just missing it both ways... if you want to walk it figure 40 minutes travel time), an hour to eat, 15 minute wait after your ADR time... I personally wouldn't make it for any later than 5:45 or 6 the latest. But that's just me, I'd rather be done early and not feel rushed then to cut it too close.
