It was Hertz. We rented from the airport , used it for a few days and then returned it to a different location (Royal Pacific but you could choose Hard Rock or Portofino as well) as far as I know it is Hertz only . No option for any of the other Universal on site hotels .Really?! That's amazing and I had no idea. Does this apply to certain companies or any of the local rentals?
PS this is why I love these boards, no matter how many times you go you can always learn something new!
