Travel out of WDW

We are planning on staying at WDW this spring and wanted to make a quick trip to Universal Studios for the Harry Potter fans in our group. We don’t need a vehicle otherwise and wanted to see what the best way to get there and back again is?

I would say uber/lyft - a regual taxi is a lot more & I can’t think of any other way you can do it if you are not renting a car.
