Oh boy! I am checking out the wait times for WDW right now to plan and prepare for our family trip to WDW. Yikes! I don't like seeing the long, long wait times. Are there any positive reports I could read about dealing with the crowds and hoping to get on every favorite ride?
Are you staying on-site? if so, the best tip is to prioritize your favorite rides and when making FP reservations, go backwards from your last park day to your first (the closer you are to the start of your vacation, the less likely those FP's will be available).
If you're going in the first week of December, crowds aren't actually bad. I had a great time when I was down there and while there was at times an influx, it wasn't hard to navigate. Caveat: I did use Touring Plans. I found it useful to have an outline of a good strategy in how to do everything I wanted, even if sometimes I said "screw it, imma do this instead". It's $15 bucks to use the planning tool, but worth it for those insights. But as I had already figured out, it's a tool, not a straight jacket.
If you're going week of Christmas, what I would do is avoid MK on Christmas Eve & Christmas day like the plague unless you plan on rope dropping and staying in the park all day (or hopping to another park).
A tip that I thought served me well: If you're going during a time where they have the christmas parties, make your MK day an
MVMCP party day even if you don't have a ticket to the actual party. Your day ends a little early but because people don't want to cut their time short in the parks, it decreases the crowd relatively signficantly. You still get hour waits (maybe a little more) on some attractions, but non-party days at MK are noticeably more crowded (to the point they have to open up a back area to bypass crowds for the fireworks in addition to the bypass by Tony's).
If it's in your budget and the it's available during your trip, get an Early Morning Magic for Fantasyland. You can get on the most popular FL rides and attractions and you get a complimentary breakfast. Takes the pressure off getting FP's for those attractions. And since breakfast is in Future World (go figure) then it's not hard to hop on Space Mountain when park opens to everyone else before getting your meal (ends at 10).
