My husband just found out he may have to cut his trip short to attend a convention for work. I just bought him a three day base ticket (no hopper, no expiration) on Saturday from the Disney Store. What are my options? He will only need 2 days now and we are not a family that goes every year. Since I assume they will not change it down to a 2 day ticket and refund my money... Am I correct in that they will allow me to add non-exp to it after the purchase? Does this have to be done at WDW? If I do this, will they let me add extra days at that point (in case that becomes a better deal). Any other option I should consider? I forsee another possible trip whenever our youngest gets old enough to appreciate it. Thanks for your help.
