Hey Amy!
Thanks so much for coming to see us today. You're definitely correct in thinking the first week of September will be less crowded than the first week of December. It probably won't be a huge difference, but, historically, the first week of September is less crowded because many kids are back in school for the year.
Other than the crowd levels, you may want to consider September versus December based on the amazing Special Events taking place. In September, you'll be able to dine around the world during the
Epcot International Food and Wine Festival and enjoy some family-friendly haunts at
Mickey's Not-So-Scary Halloween Party. In December, you'll be able to catch Mickey and his pals celebrating the season during
Mickey's Very Merry Christmas Party.
The weather will also vary between September and December. Early September is often still hot and humid, with daily rain showers. December can be a little more unpredictable, but is typically drier than you'd find in early September.
I hope this helps, Amy. Please let me know if you have any other questions!
Ashley
