www.allearsnet.com has good info on how heavy the crowds will be. I think they have low, moderate and high volume days with the corresponding dates next to them. Hope that helps you.
We will be there 12/12-12/16 (leaving on the 16 so not going to the parks)
crowd levels at a 4 which is the lowest
Just how accurate are the reports??? We were there this past Sept, but crowd levels are always low then, and the numbers were also at 4...are the crowd levels the same during that time of Dec and Sept???
