OK, it isn't even "Summer" yet, but we are already seeing a "melt-down" of the available parking.
Coming from the South to Disneyland, get off at Disney Way, head to Timon, and be told to turn around, and go park at Anaheim GardenWalk. (around 10:30 AM this morning)
So many folks, that traffic was backed up to Harbor!
So some folks said, hey, lets check out the Mickey and Friends Parking Structure instead... Well, that was the WORST choice, as the traffic was backed up on Ball PAST Harbor. And of course, made the Southbound traffic from LA also have much longer waits to enter the structure.
So you had about an 1 hour period between arrival and getting to security if you opted for the Parking structure.
Anaheim GardenWalk, closer to 45 minutes after parking, and taking the Shuttle Bus to the Security check area.
Plan in advance, get there early and leave lots of time if you plan to meet others!
