Something like a regular Lyft or an Uber would do the job at the moment anyway... there's no perk to it for Universal since their two properties are split apart.
That's a good point. I was thinking more about an integration into the Universal network. Maybe something within the app. I also like the idea of the cars picking you up outside your room. For the current resort, it's not needed as the transport is pretty good and walking is always an option but once WnW comes online along with the new plot of land, it can get a little messy.
