I second this. The first time I went from Anaheim to Universal I did this. I was pretty bummed out that we were picked up by 5pm ish.
I like staying late for the shows and rides in the night time, so ever since then, I've been back twice and have used Lansky and Lyft/Uber!
Lansky is awesome, spacious and clean. It was too pricey for 2 people. I'd recommend for a family though---then the price isn't as bad.
Lyft was easy because there are tons of cars ready around the area.
This way I got to hang out around Citywalk and soak in the atmosphere
