Probably an asked question - but I will ask anyway. We're going in early December for one last trip on our current AP's but my parents will be going with us. Now....my dad is not a crowd person at all - and I'm not sure how much he is going to enjoy it. Can you extend the number or days on a ticket after the original purchase?? Or do you need to make sure that you purchase enough days from the get go? Also - can you add the non-expiration later in the same trip if you decide that you want to do that?? I want to make the most of the money we spend on his ticket but want to have enough if he surprises me and loves it - which I'm hoping he will. The only reason he is even going is he said that he would go with us if I had a little girl
