Itinerary question

We’re planning on doing Happily Ever After at the end of a split day at MK. The following day, we’d like to rope drop Epcot. Question is, what’s the earliest we could get to our room at WL after HEA? I want the kids to get as much sleep as possible before a potentially early day the next day.

Longest time will be getting out of the park. But once you reach the boat, it is ~13 minutes. It took us about 30 minutes to get out of the park after the fireworks. But you might do better depending on where you are watching from. All said, I’d estimate about 45 minutes. ALTHOUGH, I don’t know if you’ll have to wait for the boat if everyone is leaving at the same time.
