Your tactic of buy and use for two or more trips in 12 months and then take a year off before buying a new one is a good one. We did that for years before the DVC discount and continue to do a version of that now. Our APs expire next month, but we will not renew them. Instead we will buy new discounted AP vouchers to lock in the pricek, and then we will activate them next January when we next travel to WDW. Once they are activated on January 26, we will take two more 10 day plus trips next year including New Years 2010. Then we'll likely let them expire again. Since we will likely have a bunch of banked points that year we don't go, we will probably do a Hawaii trip instead of Disney on our "year off".
