Boats from Epcot Resorts to HS?

How early are the Boats running from the Epcot Resorts to HS with the EEMH now in full swing? And is the Boat Schedule also part of the MDE App (like it is for the Buses)? It would probably be just as, or quicker, by walking from BC, but that early a.m. humidity would turn my shirt into a wet mess.

I believe I found my answer, 4:30 a.m.

Thank you! I’ve been wondering this for our upcoming trip!
