What’s The Best Time Of Year To Go To Disney?

It's hard to plan the best time to go to Disney and avoid the biggest crowds.  

Many people say that January is the best time to go and avoid the crowds.  Only problem is, kids are in school.

Another good time to go is October. But, same problem.

Many people try to go during school breaks, but everyone has that same idea.

The picture below is from a friend who thought they'd outsmart everyone and go the week after Spring Break.  Not so much.  What time of year have you had the best experience?
