I am going on the Explorer August 7-15 and we have already booked our shore excursions through Royal Caribbean. There is a lady named Claudia who is extremely helpful in suggesting accessible excursions. When I called, I just asked who handled shore excursions and told them my situation. She is the one they connected me to. They recommend some excurions you can get a private van with a lift. It is expensive though. $75 per hour. From what I understand Royal Caribbean sets it up. So we would be treated as any other passengers on shore excursions. I think you can get 2 wheelchairs and 4 other passengers in the van if I remember correctly. I will know more about this obvisouly when I return. You are welcome to email me with more questions and I will try to help you with what I find out on our cruise.
