Hi Harvey,
Can you quickly post which parks you did which day please? I had friends going for their first time that same week, and I had them all organized. I haven't heard back from them since they got back (Disney was followed immediately by business travel). I just want to see if they might have had the same experience as you.
Saturday night: MK for Electric Street Parade. The crowds were what we normally encounter during the day at that time, which kinda got my attention.
Sunday: Epcot. Had to wait for 30 minutes to get on The Living Seas...line outside the venue. Line all day at Spaceship Earth. Got FP for TT, no FP left for Soarin' by the time we go over there around 2-ish.
Monday: AK. Horrendous. Couldn't walk. Lines just to get FP. Standby at EE was 2 hours. After parade the park cleared and we were eventually able to enjoy everything we wanted to see.
Tuesday: MK. Again, our second worse crowd day. Also very hot (almost 90) so folks were grumpy. We only stayed for 1/2 the day because it was hard to move. Lines for food were really long.
Wednesday: Hollywood Studios. Longest line was for bagcheck getting into the park

The rest of the day wasn't bad at all, though more folks than we're used to. Waiting just over an hour for Toy Story.
Thursday: Epcot again. Spent more time in World Showcase, crowds seemed better, but still more crowded than we've seen previously at this time.
Friday: MK. Not at bad as Tuesday, but we still waited 20 minutes for People Mover.
If they had a plan, I"m sure they were fine, especially having not experienced Disney before and knowing what to expect crowd-wise. One of my Sons-in-law had been only once before in January 2 years ago, and he was shocked by the crowds.
