Buses to and from DS can be notoriously unreliable, especially in the morning hours. If you really want to park there, because it sounds like a great place to finish your tour and hang out afterward

, I would strongly suggest catching an Uber/Lyft to your first resort destination.
Here’s how it would unfold in my head:
Park at DS
Uber/Lyft to Beach Club
Tour Beach Club, Yacht Club, and Boardwalk on foot. If it’s lunchtime by then, there are plenty of good places to eat nearby.
From the Boardwalk, catch a bus to the MK. Hop on the monorail and tour the Poly, GF, and CR.
From the CR, take the blue flag launch to the WL. Rest, relax and enjoy the ambience there for a while!
From there you can decide whether you would like to take an Uber/Lyft to AKL (or boat back to MK and catch the bus from there, which would be free, but would take a LOT longer). AKL is spectacular, but you will have seen a LOT of great decorations by then and may want to call it a day.
Catch a bus from your last destination back to DS.
Have a delicious supper and enjoy your evening!
Wow, that sounds fun! Now I wish I were going with you. Have a great time!
