We booked everything, including airfare, through disney for our August trip. I call twice a month and make a payment with my debit card when I get paid, this way none of it goes on credit and the trip is totally paid for when we get there. The airfare was $150 roundtrip from Pittsburgh, which is really good. It was not on SW, which means we may actually get to sit together!

When we booked, we had to pay the $200 downpayment plus the airfare.
