Each member of my family has a day left on 5 day park hopper passes. I understand that we can "trade in" these when purchasing annual passes. A couple of questions, first HOW MUCH will they reduce the cost for these (3 adult, one child) Keep in mind that we have Disney Club re: any additional discount, too. Also, my son, who is 7, also has one day left on a pass of his from our next-to-last visit -- I assume that his will be adjusted for each day left on his two passes? Also, I had heard that this can only be done at guest relations at a park, but when I asked CM when making reservations (AKL for two days, then Poly concierge for two days) she said that concierge could definitely handle this for us, not sure about AKL. Any info would be appreciated!
