Because my DW is not a great Disney fan, we rotate our April vacations between 3 different locations, I know that we probably will not be back in Disney until 2007. I also know that if I wait until then to purchase tickets that the prices will be higher than they are today. Can I buy tickets now, knowing that I won't be using them for 2 1/2 years? What happens if they change the 'tickets never expire' policy? Is there some sort of assumption that if you buy tickets now, that at lease one day of them will be used somewhat soon?
