Despite the crowds our favorite time to go is over Easter break.

Sure it's crowded, but let's be honest, when is Disney really not crowded. If you go off peak there are less people, but the parks close early, some of the shows and parades are on a limited schedule, and you run the risk of your favorite rides being closed for cleaning and refurbishment.
No, we love going over Easter. If you manage the crowds correctly by going to the parks early, leave around or after lunch, then go back after dinner and stay later the crowds are not an issue. Also, fastpass as much as possible.
I will take the crowds for the better weather. I have been there at just about every time of year, I will take Easter over most times. You want to see crowds, go during Christmas. It makes Easter look like off peak!
