This past August, we stayed at a hotel on Ball Road, so we usually took the tram to and from the parks. The walkway wasn't open yet, so that wasn't an option for us.
Q1: To access the walkway from the street, I assume people would have to go up one of the escalators at the south end of the parking structure?
Q2: From what I could see of the walkway, it appears to be a very pleasant walk, as well as shorter than the "old" route of walking west to Downtown Drive, then heading south (the walkway may not be significantly shorter, but it is shorter nevertheless, plus no wait at the traffic light). Does it appear that a significant number of people who use the parkade are taking the walkway, rather than lining up for the tram?
I wonder if part of
Disneyland's plan is to save money by encouraging people to take the walkway, which would allow Disney to reduce the number of trams.
