We have APs and have been averaging 16 nights per year at WDW, split into 3 separate trips (two for 6 nights and one for 4 nights). We visit one park every day, sometimes together and sometimes going to different parks, although it may be for only 2 hours or so most of the time. I may go to a second park in the afternoon for another couple hours, but DW usually lounges around the pool reading, goes shopping, etc. We may return to one of the parks in the evening if that is the location of our dinner outing. We usually eat out every other night during our stays, and choose a restaurant at one of the parks about one-third of the time, going to a resort restaurant, DD, or off site the rest of the time. If I use a 10-to-12-hour day for park visits, we are probably in the 25% range. On the other hand, we do visit a park virtually every day during our stay.
