I'm the odd-ball out, I guess. I have park hopping with my annual pass, and almost never use it. I think a total of 3 days out of 20 that I've been in multiple parks on the same day.
Until this year with the annual pass, I've always gotten a 10 day MYW base ticket (no hopping, no water parks). I do add the no expiration option though.
What I did was to go to a park in the morning, when the crowds got bad or it got too hot in the mid-afternoon, I'd go back to the resort for a while for a late lunch and quick nap (yeah, I'm getting old. ;-) ). After, if I wanted to return to a park, it was back to the one I'd been at that morning. If I didn't want to go back, I'd head to DownTown Disney and do my souvenir shopping.
It worked well for me. The only thing is that I found after my first trip that I really needed to research crowd calendars so I wouldn't wind up in the most crowded park of the day.
