if your daughter can get around on crutches then she shouldn't have a problem, if she is in a wheelchair, she shouldn't have any troubles getting around either. The halls are wide enough and their are plently of elevators. You might want to have your TA contact the cruise line to see if there are any handicapped staterooms available. The cruise lines are very helpful when they know that they will have a passenger with mobility problems. Rembemer that kids heal a lot faster then us adults, she may surprise you! I wouldn't cancel your cruise, she has just short of a month of healing time, that's a lot for a teenager. What are your ports of call so that we may make some suggestions for excursions.??
