Correct my last comment for star ratings.
Grizzly riven run is closed and cars
California Adventure is just about always less crowded than Disneyland. Just be sure to get a Fastpass for the Cars ride.
Beware of a huge surge in crowds after Disneyland closes early for Mickey’s Halloween Party, especially on Friday nights. Everyone goes to DCA and it gets packed!
CA is quiet. The Screamer is shut however which means most people have gone to DL instead today
DCA is a ghost town after the summer season.
