Hmm...
The AP wouldn't be best for you at first glance. However if you are needing 2 days of park passes you may have several choices.
They don't sell park hopper tickets in 1 or 2 or even 3 day increments. They are available in 4, 5 and I think 7 day passes and allow you access to all 4 theme parks.
Now, those days never expire but you are forced to buy at least 4.
The price of a single day of admission at the MK is $58.31 Adults (10 and older); $46.59 Children (3-9) Epcot, MGM, and AK are all about the same within a few dollars.
So if you will only visit 1 park each of the two days, then buy the single tickets. If you want to visit more than 1 park in each of the two days then buy park hopper tickets.
The other choice is to book a vacation package, they will sell you an ultimate park hopper ticket that is good for the length of the stay. The only catch is it's a minimum of 3 days.
Hope this helps.
