Last time we used Budget and dropped off at port and rented again after to return to wdw. We were happy with them and thought the shuttle was convenient. (for anyone planning on using this route!) Be careful though, they have an unusual refueling policy. Make sure you understand it, some people got stuck paying twice!
I've used Budget in many towns before without noticing anything different, what do they do that is unusual in Florida? I'm thinking of renting for a few days before my cruise in September.
