Don't forget that you can also try and upgrade the ticket at SOG. You might be able to do it there, and if so will save a little more money. When we got this years PAPs and reg MYW 10day+s NE, they said that if we were going to get 1-9 day MYW tickets to make sure we ONLY upgraded the military tickets at SOG so we would get credit for the full price we paid.
However, last year, 2005, we got MYW tickets from our local base, and we did NOT use SOG to upgrade them... we used Disney. We got credit for more money then we had paid for them... and when I pointed this out to the WDW CM they said that they had to go with what the computer said.... so

?
This year we also used some old PH tickets we still had. Last year we took all of the tickets we had down with us, about 6 or 7 of them. And we had a CM at ECPOT run them to find out what was still usable on them... and then we wrote on the back the days and +s still useable on each ticket. And as we used them we marked off the day or + we had used. We were very carefull, almost compulsive about it all.... Well this year we tried to use some of the tickets and low and behold, 3 of them were "empty" of days and +s... and we had not used them.... so who knows what happened!? We had checked the tickets the last day of the last trip down in 2005, and have no idea why the tickets showed usable days/+s then but not in Feb and May of this year. ( DH took some in Feb and when 1 or 2 didn't work but should have he took different ones in May... and then we rechecked one of the "empty" ones from Feb and it was then good...so that is the first one he used up!)
We have had tickets checked at some of the resorts and been told they were useable, and when we walked from the Cont. to MK we found out the ticket was not useable... all in a matter of a 10-20 min walk!?

So we asked at MK, "Why did the Cont. desk show that the ticket have days/+s on it and now it doesn't?" and were told that some of the resorts gave "false" reading... but the Parks were ALWAYS correct... hahahah NOT! we used that ticket at a different park a day or 2 latter.
So it is all very confusing... and in May of this year we were told at MK, ECPOT and DTD that all old Park Hopper tickets could be used but no longer upgraded... we did not have the orginal reciept... and you might be able to do so... check at several parks, and DTD, and best of luck!
