That is for 2 adults I'm assuming. Be sure WDWPrep includes fees. $849.88 through Disney. Churning the gift cards at just 10% off (which will be very possible after the holidays due to Target gift cards selling for less ) would put you at $764.89 through Disney. I've churned for a percentage as high as 25%. My average is at about 18%. I've never used WDW Prep or even heard of them. I know
UT is reliable and easy and you can get Ebates if you use them I believe. Disney is the cheapest but it takes a little bit of work.
