DGM has cancer and legs are getting weaker. She has a walker. We will be on the Magic in Oct., wondering if DCL has wheelchairs on board to use or rent? Should we call DCL about a handicap room. Should we only take DCL excursions. Would it be better for mom. We want to go on a stingray excursion in Grand Cayman. Taxi to Sally's mini golf in Cozumel. Any help with these concerns will be very helpful.
