Welcome back! I agree with you that expecting high crowds is different than being hit with them by surprise. I'm glad that you didn't have a pity party for long though because there's always a way to enjoy WDW! Think of the fact that you were enjoying it as a DISer so you know so much more than others who would've been TOO overwhelmed by the crowds.
Anyway, looking forward to your trip report! And a happy mother's day to you!
