What if: Universal would have all it's parking off site.
For both resorts, including theme parks and hotels. A central parking hub is attached to transportation options for all destinations in a quick and personalised way.
Driverless pods would bring you fast and in 1 short ride with no stops to your destinations while providing you with information about your room or opening hours for the theme park you want to go to.
You bought your ticket and receive a tapu tapu or you already got one when you booked your resort vacation. Step up to a console and your tapu tapu knows what hotel you are staying and gives you the option to select your hotel or one of the theme parks. You also select the people in your party and 1 or 2 pods drive up and your name is above the sign, ready to go.
It would free up a lot of land to build a theme park and many more hotel rooms. These pods already exist, are green and lightweight.
