Obviously, it's not the ideal time to go from a crowd perspective, but there are things you can do to make it a fun trip.
The #1 thing...Properly Manage Your Expectations- we all want a magical trip, and while there's no way to do it all in 1 trip...you're going to be doing a lot less just due to crowds.
#2...make sure you're booking your ADRs at 180 as soon as the website flips. Since crowds will be heavy, having table service meals should spare you some of the chaos you'll get with the throngs of people lining up at the quick service spots. It will also afford you some break time from the crowds. If you're staying onsite...make good use of 180+10 booking.
#3...make your FP reservations right at the 60 day mark if you're staying onsite and 30 days if offsite. If offsite, be prepared for popular FPs to be limited. Before you book...devise a touring plan and a backup plan all hinging on the FPs you're booking.
#4...plan to get to the parks (especially MK and EP) before they open. If you're offsite, make sure you get there super early because I've heard the traffic jams can be maddening + offsite guests run a far greater risk of being shut out of certain parks due to capacity crowds.
#5...have fun- SERIOUSLY! Plenty of people on here go to WDW at this time of year and have amazing trips. They've planned properly, managed expectations accordingly, and often "stop to smell the roses" when the lines are too long. Maybe that's shopping, checking out details, riding the monorail or boats, grabbing a fun snack and people watching, or meet and greets with less popular characters. Either way, it's your trip and it can be great if you're positive about it.
If it makes you feel any better, we're hitting Disneyland around the same time. I know we'll be fighting capacity crowds, but it was the only time we could make this trip work...so we're going to try and do as much as possible, enjoy the little things, and just enjoy it for what it is and what we make of it
