Thanks Dave & Dwayne. I saw a picture of someone's wheelchair parked in front of one of the cabanas but after seeing the map of HMC, I see it looks as if there is a walkway kinda behind the cabanas. It will be easier than pushing the chair through all that wonderful, soft sand! Thanks for the links, too.
Do you know what time the shore excursion desk opens on embarkation day? Guess I need to park myself in the line so I have a chance at a rental!
