We also gave 2 of our Space mt FP out and I thought : people are going to be soooo thankful for skipping the line that already went outside the ride and into the sun....NOPE, I offered them to one couple and they refused!!!!! The seond couple, jumped on the FP.
I experienced this too...I tried to give away two FP's for Soarin, and people backed away like I was a lepper! I forgot the baby swap pass would mean that I didn;t need fast passes for everyone in my party so I had two extra, it took about a half an hour of asking everyone coming off the escalator waving the FP's in my hand before someone gratefully took them.
People looked at me like I was a criminal on time square scalping tickets or something
