Animal Kingdom to Magic Kingdom

We are going to be heading to Animal Kingdom on March 2 and staying for rivers of light. We are then going to head over to Magic Kingdom for the after hours event. We’ve not been to Disney World in a very long time and aren’t sure what the best way to get to the Magic Kingdom would be. Should we get an uber? Are those easy to grab or is the bus system better? Not sure what would be most efficiant and easiest! Thanks!

There are direct park to park buses; I would use that.

If you decide to get Uber take it to CR.
