When I read other peoples plans I always feel a bit like the odd one out, as we don't tend to work in hours.
We'll get to a park for opening, and then leave when we fancy, could be 10.30am, could be 3pm, just depends when we have done what we wanted to, or fancy heading back.
Then if we fancy, we'll head out again in the afternoon/evening.
If we have something planned for an evening I'll have in my head "oh, we need to leave for DHS at 6pm" so that'll be the plan for the day, then if we have ithcy feet earlier in the day we'll head to a park/waterpark/DTD.
I think if I got to a park and knew I'd have to be there until an ADR 6 hours later, as soon as I got hot or tired I'd start thinking "oh no, I have to stick this out for another 3 hours" and I don't want to ever feel like that in a Disney park.
We just print of Tour Guide Mikes good and bad day guide, then hit the good parks as and when we fancy.

Worked great for us last trip, and we go to see and do everything we wanted as many times as we wanted.
