Florida crowd sizes

[Beast]

While considering our next trip to Florida, we've debated going to the other areas near Disney. What can anyone tell me about what the crowds are like at IOA, Univ.Studios, Busch Gardens, Sea World, KSC, etc. during the week between Christmas and New Years???

I have two theories:
1) All of Florida in overloaded as badly as Disney is because it's a great time to go on a family vacation.
2) Disney sucks up everyone and the other attractions aren't as crowded.

I appreciate your help.

The Christmas and New Year's time frame is a very crowded time for the theme parks. You will find the parks at or near capacity. Magic Kingdom generally has the most crowds. Busch Gardens and Sea World generally have the least. So while all parks will be crowded, you will find larger crowds generally at all the Disney theme parks.
