A friend just rented one during our stay in Southern Oregon (I know it isn't Orlando). She requested a mini-van and was given a Flex.
We all liked it but the storage area in the back was really small. The rental was to haul 6 people around...not luggage, so it worked for us but I wouldn't opt for it on vacation because it might hold two regular suitcases with a couple of soft items on top.
Definitely not enough luggage space for our family of four never mind if there are more people involved!
