Is there a slower (or at least less crazy) day of the week to visit Universal Orlando? I realize that WWoHP draws crowds regardless (and that's certainly where we're heading first), but I want to get the best/easiest bang or my time and see as much as possible aside from that.

Trips planned are :

One day/One park to IoA in mid May

1 1/2-2 days/Two parks in early September

I appreciate any advice.
