What is US like crowdwise during Christmas?

[IloveWINNIEthePOOH]

Is it any where near as crowded as the Disney parks? We will probably end up going during the week between Christmas and New Years. What will the crowds be like?

TIA for the help!!

I stayed in Orlando last year between Xmas and NY. US and IOA were busy but I didn't think they were too bad. Even Disney, other than the MK, wasn't too bad. The cold weather though may have kept people away or not in the parks as long as they were normally be. I left Seaworld because it was too cold. I suspect if the weather had been warmer, the parks would have been busy but cold and rain tends to keep people inside.
