Looking to book a car through this website. There seems to be a few pick up points along I-Drive. Let me know if I'm missing one or two, or any of the below aren't actually on I-Drive

Orlando - Coco Key Hotel, Florida
7 min / 1.5 mile

Orlando - Four Points By Sheraton, Florida
9 min / 2.4 mile

Orlando - Hyatt Regency Hotel, Florida
6 min / 1.0 mile

The Hyatt is closest to my hotel.
What I am wondering is which location has largest stock? I want to boost my chances of getting a Mustang. The booking will be made through this site with Alamo. If one location doesn't have it but one of the other pick up points does have a Mustang available, would I be able to go there on the day given the short distance between each point?
If not then what is the best location to book with

Thanks
