The time frame between Christmas and New Year's Day is arguably the busiest (or the second busiest) week of the entire year.
Disneyland often closes when it reaches capacity -- and that can happen early in the day.
However, don't let that deter you. A lot of people elect to visit the parks during that time frame anyway, regardless of the crowds, and with the right planning and preparation they have a great time. In fact, some of our DIS'ers visit during that time frame every year.
This year is Disneyland's 60th anniversary, and that is a big question mark in terms of how it will affect crowds for the rest of the year. There are new events happening specifically for the 60th, and those new shows and events could increase crowds -- but I think they will be worth seeing, as they are not going to run indefinitely. They will end or have a reduced schedule at some point next year, I'm sure.
I think that if you love Christmas and the holiday season to begin with, you shouldn't miss an opportunity to see Disneyland Resort (including the 3 hotels) decked out in holiday splendor. It is truly amazing. It's a Small World Holiday and Haunted Mansion Holiday are worth the trip just on their own!
If you don't care too much about Christmas and just want to be in the parks when the crowds are lighter, then go during the January timeframe.
Be sure to join us in the Disneyland at Christmas/Holiday Season Superthread if you have time -
http://www.disboards.com/threads/di...erthread-5-awaiting-details-for-2015.3358217/ - and feel free to jump in and ask us questions, and/or peruse the posts on page 1 of the thread to learn about holiday activities, decorations, dining, shopping, hotel fun, etc. We're there in that thread all year long, chatting about the holidays and discussing breaking news, rumors, speculation and so forth. So far we don't have any real news about this year's holiday season, so you will see a lot of references to last year's dates and events. I will update the info on page 1 as new details come in. (Also, please forgive any weird punctuation or tiny font that you may encounter, or links that don't seem to link to what they're supposed to link -- those quirks are the result of this website switching to a new hosting platform earlier this year, and a lot of formatting in a lot of threads across the entire site was compromised. It will take a while to clean up!)
Edited to add: I moved this thread to our main Disneyland trip planning forum and out of the Disneyland Community forum.
