I mean how many cars are used solely to drive from the airport and then sit in a hotel parking lot for the next week only to be driven back to the airport. 50% seems a conservative number considering that resorts like Disney world have their own transit systems.

There are plenty of attractions outside of Disney or Universal. I'd guess no more than 10% of rented cars have zero activity.

Regardless... these are families who live in South Florida. Cost of driving is a tank of gas each way. Can drive right up to the hotel's front door, no Uber. Can visit both Disney and Universal. Mom or Dad can easily go to convention while kids go to parks, etc.

It's a very rare confluence when paying more and giving up the freedom of a car makes much sense.
