My dad HATES Disney, but when they went with us several years ago, he loved GF. I know that 4419 in RPC is HA and connects to 4420. These are very large deluxe rooms with two Queen beds and a Queen size pullout sofa. They both have wet bars with a mirror and an extra sink too. The HA has a huge roll-in shower and 4420 has a large soaker tub

They are the first two rooms in the hallway directly off the lounge, so this would be very convenient. I think getting a room with a King bed may be more difficult since all six king turret rooms do not connect with another room. I don't know if any on the second floor king rooms connect, but I wouldn't want to be on the second floor. To get the king bed, perhaps you would have to get a suite?? Plus Disney doesn't guarantee connecting rooms, as you know, but surely they would make an exception under your circumstances. I haven't stayed at CR CL, but I'm sure Trish is right about it being great. But the nice thing about RPC is that you would at least have the band to entertain you in the evening. I do think the monorail is pretty easy with a wheelchair (we traveled with my MIL on a
scooter a while back). Good luck with your decision! Keep us posted!
