Marriott is definitely not a nickel and dime program. I should have clarified that better.
I hope they don't go the route of Wyndham or even Hilton for booking fees.
You did select the highest category room 2 bedroom at SSR during the 2 highest point season. But, I can play with those numbers too. If SSR is the choice standard rooms still come in at $1737. Animal Kingdom Lodge value two bedroom would cost $1,642 during this same period. Most people staying offsite rent a car if they are flying. $20 each day parking Fees at Disney, gas and tolls would easily put you around $350. I know Marriott doesn't have resort charge fees, but some timeshare do. Knock $350 in transportation fees off and you are right at Marriott cost during peak season. Conversely, if you go in December or November (when most DVC members prefer to go), the DVC maint fee for that 2 bedroom is 18 to 20 percent cheaper putting it as same value as Marriott before transportation savings.
My point is it's impossible to look at a room to room cost when comparing DVC vs any other program. A better comparison would be for you to look at all Disney costs and tally those against DVC (food, transportation, and tickets).
If my DVC membership saves me 10-20 percent off food and souvenirs, $200 off annual pass tickets per person, and $300 in transportation costs per trip when compared to other programs (not just Marriott), I think DVC will prove its value financially.
As far as my twenty percent disney savings buying disney gift cards to pay for my maint fees, if the local grocery store sells Marriott gift cards and Marriott owners can use them to pay their maint fees, that would be an equal savings. Maybe someone is currently doing that within Marriott's program.
My point was to illustrate total savings to show you that DVC maint fees cover much more than just a roof over your head, so how could you compare DVC maint fees to offsite maint fees that only cover the roof over your head?
