We've only gone to WDW a handful of times for the weeks around Labor Day because of the heat.
My list of- On the bright side of things:
1. It is a time of the year that icy drinks are very enjoyable! (I would say mandatory--find out where the frozen Cokes are!)
2. Afternoon breaks are a real blessing and staying on property makes it very convenient.
3. For the week before and after the actual Labor Day weekend, the crowd levels
can be lower (relatively speaking). A lot of kids have returned to school.
4. You don't have to pack a coat or warm clothes (like if you go in winter months--yes, it
can get cold).
5. You
might not mind getting wet on Tiana's Bayou Adventure or Moanas Journey of Water or Kali River Rapids
