Have any of you traveled with someone needing extra help with mobility?  Or, perhaps you yourself need extra help.  Do you find that the crew goes out of their way to assist?  I know that there are specific cabins for those in wheelchairs which is great.  I know that elevators make getting around the ship easier.  Is the handicapped passenger given seating close to the door in the MDR? Do you receive help exiting the ship in ports?  On tenders? In the theater?
