You can also take the Skyliner between EP and HS. It takes you to the Riveria Resort, then at CBR you need to disembark and enter a different queue to hop on again. It was my experience that Skyliner took longer from HS to my resort (BC) than the boat, but I'm not sure about gate to gate from HS to EP. I think it would depend on the time of day and the length of lines at the CBR for changing gondolas.
