Simple question: do buses run between Beach Club (or other Epcot resorts) and the TTC? I’m guessing not, since buses go to the MK entrance from there?
It looks like there isn’t a direct route to the TTC from Beach Club; you would need to make a transfer.
Here is a helpful website for transportation for WDW: http://www.ourlaughingplace.com/aspx/twiz.aspx
Cool! I hadn’t seen this before. Very useful, thanks!
