we just returned from Disney and had 4 gad vouchers that we used for fastpasses, 3 times we had 5 in our party and used them no problem, On our magic Kingdom day we had friends join us (august 29) so we had 8 people all together, I had a very unpleasant cm who looked at my 8 kttk cards and handed me 2 back and said I could only have 6 fastpasses, I asked if I could please have 8 as I knew it could be done and she refused, I asked to speak to the manager and explained that our friends had arrived later to the park as we thought we would have the fastpasses, she whispered with the cm and turned to me and said "I wouldn't feel morally right if I gave you 8, you are only allowed 6, I was very pleasant through out and basically begged her as the family with me was upset as they would have got there at ropedrop other wise, needless to say the manager still refused and only gave us 6. I have no problem with a rule if it is the same all across the board, I was even more upset when I was talking to someone on the monorail who got 12 at Epcot the day before. So its never guarenteed you will get more than 6.
