Is the first week of "Halloween Time" at Disneyland California (roughly the 15th-21st of September) more crowded than the second week (September 22nd-28th) due to the decor being new or are they about the same? THANKS in advance!
In my experience the first weekend tends to be a bit busier what with the opening of the annual offerings like Space Mountain Ghost Galaxy and Haunted Mansion Holiday. Then after early to mid October, it gets progressively busier up thru Halloween. Keep in mind, there are very few blockouts during this time so the parks will still be busy. The Halloween parties tend to be less busy earlier on and get more crowded up until Halloween.
