Welcome to planDisney, Emmanuel and Happy (early) Holidays!
Emmanuel,
Disney's Wilderness Lodge is one of my favorite
Disney Resorts Collection hotels and it's certainly at its best adorned with all the Christmas trimmings. I have fond memories of visiting with my family around the holidays and took quite a few photos of my little ones in front of that huge tree in the lobby!
Emmanuel, unfortunately I don't have a date when the holiday decorations at Disney's Wilderness Lodge are guaranteed to be up. Some years this resort has seen its Christmas tree installed close to Thanksgiving while other years it hasn't been until early December. If your travel dates are flexible, I would encourage you to consider visiting early in the month of December when your chances of enjoying this resort fully immersed in holiday décor are greater.
Emmanuel, I'm sorry I wasn't able to give you a more definitive answer, but do hope this helps in your trip planning. An added bonus of traveling to the Walt Disney World Resort around the holidays is the mild weather, perfect for the
boat ride to Magic Kingdom Park!
Wishing you all the best as you continue to plan for
the holidays at the Walt Disney World Resort. If you have any other questions I hope you'll come on back to planDisney where we love answering guests' questions even more than Kristoff loves Sven.
