EMH's in the Parks
We like to be 1st in line.

What is the earliest time a bus, boat, and monorail arrive at a resort to take you to the Park which has EMH in the AM?

That would be a boat from WL, CR, GF, Poly to MK.
Or a boat from BC/YC, S/D, BW to DHS & EPCOT.

Monorail from GF,CR, Poly to TTC to get to EPCOT.

Bus from all resorts to MK, EPCOT, AK & DHS.

Do they start running at 5:30 AM? 6 AM? 6:30 AM?

 

[Robo]

Buses start running about 6:30AM.

If a park's AM EMH starts at 7AM, the buses will be rolling even earlier that day.
