My husband has only one lung (surgery for lung cancer) and problems with his joints after chemotherapy so cannot stand for long periods or walk very far without resting but does not need a disabled cabin as he can shower in a normal shower or use a bath with shower over. He uses a Travelscoot (which we first saw on a CC forum and then imported from the U.S.) to get around on land but does not use it on board as he uses a shooting stick which has a seat on it. We wanted to go on a P&O cruise from the U.K. but were told we had to book a disabled cabin or a suite if he wished to take the scooter with him. We cannot afford a suite and he does not want to take the use of a disabled cabin away from someone who needs it - therefore no cruise with P&O. We have sailed with Celebrity where there was no problem but they have limited cruises commencing in the U.K. So this year no cruise.
