Disney is such a "first marathon" or a "once and done destination" race that I doubt prices will come down in the near future. When I ran my first marathon at Disney I never even considered the cost. I so much wanted to run the Disney marathon. That is the way with many of the runners. They don't pay that much attention to the cost because it is Disney, they want to experience it and it will most likely not be an annual event.
For us crazy people that like to go back and punish ourselves each year it is a different story. We look at cost because it isn't that once in a lifetime event.
I just checked prices for the Florida 70.3 tri (which I will run in 2011) and it is $260 plus Active fees on top. That is this year, I am sure next year it will go up. Do I care? Nope because I really want to participate in that race. next time I might care, but this will be my first half Ironman and I am willing to pay what it cost. And to think, no characters or other special Disney stuff.
enjoy,
Duane
