Yeah, I have tried that. But there are no discounts like if you go through Priceline or something similar because you can't specify the address.Google this: hertz at universal Orlando
and you get this:
https://www.hertz.com/rentacar/location/unitedstates/florida/orlando/orlc32
My guess is that they deliver the car to the hotel from another location.
because you can't specify the address.
