I was looking to hire a mobility scooter for my mother on a cruise from Southampton in the UK. When searching I found a link on the UK version of the Royal Caribbean website (Cruise Ship Accessibility - Royal Caribbean
) to RentaScoota who are based near the port. The page all about their service can be found here Mobility Scooters Hire for Cruises from Southampton - Mobility Scooter Hire Southampton
I know this is a little off topic as not Ft. Lauderdale, but if it could help anyone from the UK who may read this page.
