AP's definitely enhance our WDW experience, especially since we have young kids.
We basically just do the parks in the morning for about 2 hours and when the kids get tired we head back. Afternoons are filled with other activities like swimming, etc. Sometimes, we head back later in the day to catch the fireworks, etc., but DD was scared of the noise last trip and we are usually pretty tired & lazy by then! If we were using PH, we wouldn't go into the parks on those days. What! $50/pp to ride Dumbo 2x's and the Carousel 4x's?!!!
DH & I bought AP for our trip last Nov/Dec. Older DD was under 3 at that time. I took her down (left baby with Grandma & DH) again to meet up with cousins for a few days in March. Our family of 4 are going for 13 days in September.
We were originally going to skip next year and plan a big trip in 1/2004 to start up our AP cycles again. But then I have to buy an AP for my 3 1/2 year old DD this trip. She's tall for her age. No way was I going to try to pass her off as under 3 as many have suggested. (For 13 days!!!

) Even if the CM's let me, I would be too nervous to enjoy my trip. So, my DH o'kayed a quick trip next May - because 16 months between trips seem too long and DD will already have the AP.
So, we may only go to the parks 2 days next May to use up leftover PH from before we started buying AP's. Or maybe we'll just wind up getting AP's again since we are going again the following January. This way we can go into the parks everyday in May. Not sure what we're going to do yet. It would just be nice if all our AP's start & expire together instead of overlapping. Ahhh,... but my 15 month DD will be 3 soon enough!
Another great thing about AP's that enhance our DVC experience is that last minute, spur of the moment trips are a great possibility. There's nothing like finding cheap airfare ($110/pp rd.trip LGA-MCO) for planning a last minute Disney trip. Admission and accommodations are prepaid so we only have to worry about transportation & food.
3 of my TOP TEN things I would hate to live without - my TIVO, my DVC, & my AP!!!
