We usually do the first half of the day, break, and then return. Works well for us.
We're going about that same time. I'm not looking forward to the crowds.

We went this same time last year and the crowds were awful. I imagine that with the 50th celebration, the crowds will be even worse this year.
We're only going because the DD is out of school and my wife's business is closed, so I'm the only one that is effected by going during this time.
But, the one good thing is that I get to plan our next WDW trip and I'm picking the least busiest time of year to go. We're missing school, work...whatever it takes!
