If you are scaling back the number of trips the the non-exp ticket may be the way to go. The non-exp vs discounted AP subject comes up with fair frequency and I tend to waffle back and forth on the subject.
If you are a waterpark visitor the 10 day plus water parks non-exp is pretty attractive, especially since they have 10 water park entrances. We tend to do Sun-Thurs trips and we could fit several trips in with those tickets if we did two theme park days, two waterpark days and one resort/DTD day. We have never done trips like that though, but we could.
I did the AP for our June 07, Feb 08 and June 08 trips plus my DW and DD went for one night in April of 08 on their way to
DCL. We really enjoyed being able to just go to a park for a few hours and not feeling like we "wasted" a park day on a pass. We are going to Vero Beach in a couple of weeks and don't have to worry with tickets this time!
