Both last year and this year I was at WDW for the marathon. Last year I used points for a 2 bedroom and had 5 friends with me. I did not charge them.
This year I had 8 friends come down so I had to get a 2BR and a studio. I did not have enough points for both units. My friends insisted on paying this year. We were there for a week, so what I did was charged them each $200 for the week. I took that money and used it for a down payment on an add-on. With the developer points, I was able to get both units for the week on points. I figured the monetary cost was about equal to if I had to pay cash for the weekend nights on the 2 BR and studio.
And now I'll have more points available, so when we go again either I won't have to charge them or it'll just be the "buy me dinner" exchange.
