Got our PAP at SOG in May o4. It was a lot cheaper then anywhere else.
Check with all the MWR's you can. I checked the one in Norfolk,V and it was not cheaper then here in Chas. SC.
But the MWR at the Chas. AFB was more then the Chas.Nav.Base.There is about a 6 linear mile dist. by the map.So the navy is "farther" away from WDW.
Go figure.
There is a Navy training base in Orlando, found it on line. It had prices a little cheaper then SOG in May.
I talked to the MWR folks in Norfolk, here and at the AFB in Greensboro,NC. They said that it used to be that Disney discounted the price they paid depending on the distance they were from the Parks....
This was 1-2 years ago.
You need to do a little web checking and calling. I got "old" park hoppers at the Chas. Navy MWR they were from the last order of tickets and they charged me what they paid, they pass on the cost increase when they have to pay more. Don't know if any other base MWR does this or not.
Best of luck.
