Hi Tammie! Welcome to planDisney!
Park hopping around the Walt Disney World Resort theme parks sounds pretty dreamy right now! You will be hopping and exploring in just a few days. Hooray! I know you are busy planning all the details and
counting down the days.
I am happy to report that, yes, buses are running from park to park once park hopping hours begin. I used this
mode of transportation to park hop a few times on my most recent visit last month. It made getting around a breeze! In my experience, the buses ran around every 20 minutes, give or take a few minutes. The timing of the buses can vary, so there were times that multiple buses came for one of the theme parks within a 30-minute time frame, then others where we waited up to 30 minutes for a bus to come by. Hopefully, you'll experience the shorter wait!
I hope this helps as you plan your transportation, Tammie! Please let us know if you have any other questions.
