Thanks for the reply rlp! Our Ubers took us to the guest drop-off on Harbor Blvd (below), but there is also a drop-off near Downtown Dr (also below). We did not specify a drop-off location on our Uber request, we just put Disneyland Resort.
If you wanted to be dropped off on the west side near the Downtown Disney District, just select your Uber drop-off location as Passenger Drop-Off (that is the location on Google and Uber). The drop-off is located right behind ESPN Zone and just west of the Rainforest Cafe.
We were bummed that they put the fence up around the employee parking lot, but thankfully we were still able to take the tram. It is really convenient to park in the Mickey and Friends structure, but it is also pretty expensive to rent a car and then pay to park at your hotel and the structure. We find Uber to be less expensive, especially if we are splitting the charge. It really depends on if you drive or fly to California!
