I used the Mickey and Friends garage yesterday. Got there before the garage was actually opened, but once opened, it was quick to park and get down to the tram. Got to the front gate quickly with no problems. Howerver, as the day went on, I went through Downtown Disney once for a late lunch and noticed there were some long lines for the tram. At about 7:45, I went back to my car to retreive my sweatshirt and a bottle of water. I thought it would be a quick trip, but I had to wait a long time for a return shuttle, as there were a ton of people arriving to the parking garage that night and it was a long line. I left about 10:15pm to go home, and while there was a wait for the tram to get back to the garage, it wasn't awful. Next time I will definately do the Toy Story lot. The tram service seems to be run so poorly!
They take so long to load the tram, then once it's loaded, they still sit there for a minute or so before the cast member at the back of the tram finally gives the all clear to the driver. Then, instead of having another tram right behind it, the follow up tram has to wait on the other side of the "circle" drive until the filled up shuttle leaves. Then they load, and wait and wait...then finally leave. It just seems like they are not very efficient. And, it seems like you could have multiple pick up locations during the busy times. At the Downtown Disney drop off, I guess they used the multiple pick up points at the end of the night, but there didn't seem to be double the amound of shuttles. I am all for safety, but it seemed like they were WAY too cautions of loading, unloading, and spacing between trams. I think they could still be very safe and just be more efficient.
