We are going the week of MLK but our first day in the parks is planned for Tuesday. If it is anything like WDW (which is where we usually go in Jan) Saturday and Sunday will be heaviest and Friday and Monday not as bad. On Friday lots of people will arrive later in the day so if you can get an early start you can probably get a lot done and then on Monday people have to head home so as the day goes on Monday it seems to lighten up some. I'm hoping the crowds drop a lot by Tuesday....
