I actually went that same exact time this summer! It was busy but not nearly as bad as it normally is in the summer. I was able to walk around and enjoy the parks and not have wall to wall people. We had three day park hoppers and rode ever ride multiple times and saw all the shows we wanted to without a problem at all. The secret is to get to the park as soon as it opens when it's not crowded at all.
The longest we ever waited in a ride was 20 minutes for Indy and that's because it broke down when we were in line. The one with the longest line throughout the day was probably splash mountain followed by space mountain becuase it just opened. We rode splash about an hour after the park opened and walked onto the ride.
I loved going then the weather was still nice (a little hot but being from arizona it was nice) and the crowds weren't that bad at all. I would go that time again next year but I can't convince the boyfriend that going to
disneyland more then twice a year won't take the magic away from the park.
