I love your husband's thinking!

Thanks for the laugh!
I have an AP and go to WDW several times year. I always try to go the week my current AP is expiring so I can get one last trip out of it, then let it expire, and buy a new one several months later when I go for my next trip. This past Oct I knew I had to get a new AP, had an old gift card with about $130.00 on it left over from the F&W Festival the Oct before, and had an old unused one day ticket that I had bought several years before in order to get
free dining that year. I figured out how much a new AP would cost, then subtracted what that old gift card and old one day ticket was worth and then cashed in just enough Reward Points to get my AP. The first day we went to Guest Services and turned all three in. The CM said I owed a grand total of .76 cash for my AP.
My husband and I are going to WDW in May and recently bought two more gift cards with $300.00 on each just to use for our restaurant tips and any extras we might want to buy at the restaraunts (we're on the basic
DDP) during the May trip. I'm sure we'll have quite a bit left over on at least one of those cards. I'm debating on whether to use the left over gift card while I'm there in late Sept/early Oct for the F&W Festival kiosks or save it until I get another AP in Dec. I still have several of those old one day park tickets I've had to buy for different promotions and I currently have about 500 Reward points on my Visa. I could again combine what's left on the Disney gift card, an old one day ticket and some Reward points to get another AP when I go back in Dec. Hopefully my AP will cost me less than $1.00 cash that trip also.
I use my Disney Visa for everything just to get the points and then go online and pay it off once a week. I use it just like a debit card subtracting it from my check book everytime I use it, then placing a little check mark by each item in the check book as I pay it off every Monday. As long as the place doesn't charge a fee for using a credit card I charge every thing. That way my Reward points really add up.
