Where to go on Thanksgiving Day? Sea World or Universal?

[jnhsiburt]

I have never been to Sea World or Universal and were planning on visiting each of these to parks over Thanksgiving. We are going to be in Orlando late Wednesday and returning home on Monday morning. Planning on visiting MK on Sunday and bought tickets to the Very Merry Christmas party.
We will be there for 3 other days and deciding when to go to Sea World and Universal. Any suggestings from you all would be much appreciated!
