There is a company called Care Vacations, you might try them for cost. They work with the cruise lines and local suppiers.
You do need to inform special services on the cruise line you have chosen. Also get the name of the company that Care Vacations uses for San Diego and follow up..

rent a scooter where? Just for the record - they are very dangerous and cruise line crewmembers are often forbidden from riding them. My ex-girlfriend was a professional dancer and she racked up her knee on a scooter in Bermuda.
