Wow, thanks for all of your responses!
I will take a cab - like I do for all my dinner reservations on most of my vacations. My feet will need all the rest they can get and, after having changed into a decent outfit, I'm not going to feel like working up a decent sweat again.
I'm very happy with my monorail resort - but of course, nothing is ever perfect.
I believe the Boardwalk is within walking distance of Beaches and Cream? The ice cream is calling my name, lol.
Thanks again for all of your help!
