We try to put part of our vacation budget for each trip towards tickets. that way we are done with the tickets we have we have cash to buy the new ones. we have some AP vouchers in reserve and some 10 day park hoppers partially used. IF we are planning enough trips during the year to make the AP worth it we use them if not we go to the 10 days. Obviously buying ahead save some money.
Seems like you could save some also. the only question I have is to look at your traveling habits to figure if AP's or MYW tkts work best. If we go one year late FEB we will try to do a early FEB or JAn the following year so we can get the most value from our AP's
