The wife and I decided to reserve a seat at Hoop Dee Doo, but we want to know the easiest way to get there. We're staying at POLY, so monorail to MK, then the bus? Or is there a quicker way?
Yep Monorail to MK then boat to Ft. wilderness stop (not Wilderness Lodge stop). Also to add if you have a car just drive to Ft. Wilderness and take the internal bus to the venue. That's what we always do being we have our car.
You can also catch a boat from the Contemporary if you are not going to the park that day. We often have a drink at the Outer Rim or the pool bar then walk down the dock to boat. Heading back (after the late show at least) they have buses lined up to get folks to where they are going.
Technically, you could also take a bus from MK, but that would drop you off at the opposite end of Fort Wilderness (away from Pioneer Hall), which would then require you to walk or take an internal bus to Pioneer Hall. The boat docks right near Pioneer Hall, plus it's a lovely ride!
