Well, since you are going in July, you may want to split your days up, so you aren't in the parks all of the time during the really hot parts of the day.
I would go in the early mornings, and leave around 11, then to resort hopping, have a leisurely lunch, visit the pool, go to DTD, do Disney Quest, etc.
With 10 days, (never had that luxury), we would probably do the parks in some form at least 8 of them, then use the other 2 to chill out.
