Yes, you can definitely walk from the International Gateway at Epcot to Cape May at the BC! It truly is about a 10 minute LEISURELY walk, and a really pleasant one as it is never a crowded walkway. We were at the BWV last April, and did the walk to the Beach Club a few times, for the Cape May character breakfast, for lunch at Beaches n Cream, etc. But if you are really tired, take the boat and enjoy the ride!
