I did this in November 2019. I looked at a few options. The tour companies didn’t have schedule flexible enough for my Universal park touring (i. e. rope drop, leave at park closing). I ended up renting a car for the day. Picked the car up first thing in the morning and dropped it off whenever I got back that night. I don’t remember the car rental company but it was on Katella, only a few minute walk from DL. It was less than $30 to rent. Hope this helps!
