We did a similar thing. Last August we were on my brothers wish trip and we were on RSR one morning and it broke down right after Luigi's but before the race. We got excited off the ride and we're given FP for RSR. We hung on to them and went to eat at Goofy's kitchen. When we went back to cars land later that afternoon we had the passes we didn't know what we were going to with. We skipped the line with the make a wish pass and got off and began looking for the perfect people to give them away to. I wanted a family to get them. Eventually we found a group of five people for our five fastpasses. It was a grandma, a mom, and her three children. There were sitting on a bench next to Cozy Cones when we asked them if they liked the new cars ride, knowing by the kids demeanor they had not gone on it due to the three hour wait in August. When they told us they weren't going on it due to the long wait, we gave them our makeup fastpasses and the looks on the kids faces said it all. They grabbed their grandmas hand, pulled her up, and they we're basically dragging her onto the ride.Had kind of forgotten it until this post, but one of my better memories in Disneyland.
