Heres the way that we look at it. (Granted we live only 30 minutes from US/IOA)
Forget the perks for a minute.
At the current rate to enter the park,for 2 adult 2 park 2 day ticket is 270 for the March trip. The Feb 12 trip, assuming the standard roughly 10 dollar ticket price increase, makes it 290, for the same tickets. The price would be roughly 560 dolalrs give or take for both trips.That would make it roughly 70 dollars per day per person. To add a 5th day(1 day for 1 trip only) or a 6th day,(1 day on each trip) It would be another 112 per person,or 224, and 122pp or 244 (assuming the 10 price increase for 2012)for a total of 468 additional dollars, for 1 more day on each trip.(paying after you already buy the 2 day 2 park) Youre now at 1028 total for 6 days on 2 trips, or 85 per person per day.
For 2, 3 day adult tix its 145 pp or 290. For the Feb 12 trip it would go up (assuming 10 increase) its 155 pp or 310 total. Thats a total of roughly 600.(without knowing which trip youll do 3 visits if any)
For the 4 day trip its 75 pp per day
For the 5 day its 60 pp pd
For a Prefered AP its 220 per person or 440 for both of you (roughly). That would make it 55 per day per person. (At the current rate)
So in that case, if you were looking to save money on tix, youd prob be better off buying the prefered ap, as the better deal in cost per day. The prefered would also give you %10 on meals and merchandise, along with free parking. As an added bonus, if you decided to do more then 4 days, you cost per day drops even more. For 5 days it would be 44 per day per person.For 6 days its 36 pp per day.
The Premium Ap, unless you were coming down monthly, staying on property, going to
HHN etc, isnt really a benefit for you in your situation.
