We rode once from HS to Epcot and it was not my favorite experience. The skyliner kept stopping for 3-5 min every 10 min for whatever reason, so you're stuck in the air over an over again, plus the thing was swaying back an forth. I think it took us over 40 min, bus would have been faster, but the buses drop you off at the front of the park so, depending on where you want to start at Epcot will depend on which is the best form of transport. I felt like I could have walked to Epcot from HS an got there faster though. We walked from Boardwalk to HS early that morning to beat all the buses, skyliners, and cars an it only took 10min. Got there 1hr 30 min before open and cast member stopped us near the entrance, we were the 1st ones there.
