What day in Disneyland Park (Anaheim) crowded, this Saturday (August 22) or Sunday (August 23)?

They will both be busy, but of the two Sunday will be more crowded. The primary reason is because on Saturday 3 of the 4 Annual Passes are blocked out, on Sunday only 1 of the 4 are blocked out. This last week was the first week that the So Cal Passholders were not blocked out and every day they had increased(very increased crowds). Enough that they had to extend the hours of CA Adventure by 1 hour(to 10PM) and added a 3rd Fantasmic show several nights this week. In addition parking is at a premium so expect extra time to park. If you are in one of the perimeter/alternate lots(Buzz, Pumba, Simba, Convention Center, GardenWalk...) rather than the Parking Structure expect additional time to get from parking to the parks.

Disneyland's never not crowded lol. But it depends, go early morning - as in, get there 20 minutes before they're open - helps a lot. Saturday would probably be the most crowded out of all though. Sunday just has a lot of families with younger kids that can't go on the bigger rides there, which frees up space.

Both days. This weekend is the last 2 days of Summer Nightastic which features the Electrical Parade, the new Magical fireworks show and Fantasmic. I visited this past Tuesday and it was very crowded. I assure you that, those two dates are going to be hectic due to Summer Nightastic and also because of the annual passes!

saturday. always saturday because it's the middle of the weekend and all the locals will be out in force, lol. sunday's better because it's the end of the weekend and there's, jobs, raising kids, etc. so it'll be less crowded.

i think sunday cuz socal annual passes arent blocked on sunday the park has been full of mostly socal annual pass holders this week including me :) but saturday is most likely still gonna be crowded...socal passes have been blocked all summer btw
