How crowded are parks in July?

[ufgator]

I've never been to WDW during summer b/c of heat and people. But we're thinking about going for a weekend in middle or end of July. How crowded is it? I know it will be hot (we live in South Florida). Thanks for any info.

We leave tomorrow - I know it will be hot and crowded but I still cannot wait.
(At least the hours are extended in JULY and if it rains it does not matter much!)
