We've been in the middle of November, and had shorts weather during the day. We always have sweatshirts and/or windbreaker with us because it is cooler in the mornings and night. Maybe capris instead of shorts may be a good idea so you don't overpack. Best to check the weather forecast. If you go to accuweather.com and type in Lake Buena Vista, FL, they will start giving out a forecast for that time a year 60 days out. You can even look back and see what the weather was like in November of last year. That might help. Whatever the weather though, you will have a great trip!
