Yes it would save some walking if you are leaving Epcot and are in the World Showcase, if in Future World, it won't...BUT, HS would have to have closed recently or still be open...we thought that sounded like a great idea on our first EPCOT night as we watched Illuminations from Tokyo Dinning and walked to the International Gateway and were told that since HS closed at 8 the buses to CBR would be done running from there by the time we arrived...and we would be stuck needing to call a cab...so make sure HS will still be open.
Thanks for the response. And for the other response as well-sorry, don't know how to quote 2 posts!
It would be for mid-day rest time, so we wouldn't have the worry on if DHS is open. Possibly it will be a wash distance-wise if the DHS bus stops are farther than Epcot. But I think we will try it out anyway for the experience if there's not a long wait for the boat. Thanks all!
