Signage: Being a Northern California native, I knew how to get to the Presidio without any problems. But, once on the grounds, direction signage for the museum is almost non-existent. Driving directions provided by the Museum web site just link you directly to the Presidio web site which weren't that good. Once you find the museum, the sign out front is pretty small. (I realize this isn't Disneyland and I shouldn't be looking for some gigantic landmark such as Space Mountain to find my way. I just feel this is an area that needs improvement.)
Parking: Tons of free, self-parking right in front of the Museum.
Staff: During our visit there was was a ton of very friendly and informed staff members on hand. The Museum also did an excellent job with the pacing. Never at any time did I feel that I couldn't view any of the exhibits and displays due to crowding.
The Building: The Museum is housed in three old barrack buildings that were constructed in the 1890s. While the outside of the buildings show charming simplicity in their brick structure, the inside is completely modern. The buildings are also interconnected, so you never have to leave one building to enter another. At one point, you walk along a hallway with a glass wall and an absolutely stunning view of the Golden Gate Bridge. The weather was absolutely perfect during our visit offering a breathtaking view.
The Displays: Having a very extensive Disney book collection, I often see the same photographs over and over. I would estimate that for every one photo I recognized in the Museum, there were 10 that I had never seen before. The displays also range from traditional museum displays to very high-tech, user interactive. The Museum is laid out in a timeline of Walt Disney's life. And, as with any timeline, no time travel is allowed. (You can't skip rooms). My favorite room has to be the era between mid 1950s to mid 1960s (Mickey Mouse Club, NY World's Fair, Disneyland, etc.)
Gift Shop: This is probably my only really true negative. While the Gift Shop was stocked with very unique items, I over heard the employees say several times "That's our last one" or "We're sold out". Also, the companion book for the Museum will not be available until mid-October. This is an area that will need some fine tuning right away.
I'll definitely be going back.
