I just got back from disney and purchased a 10day plus pass with no expiration. I am planning on returning next year and going on a 3 night disney cruise. I just booked the cruise thru an agency(not disney direct). I know that I can get my $back and rebook. This agency was the cheapest that I found. Since I will be returning within the year, should/can I upgrade my tickets to AP? When/where can I do this? Can I just upgrade one of our tickets for the discount? We are traveling with my sister and her family. Can I get the discounts for her also? My plan for next year: disney 8nights disney cruise 3 nights Would it be cheaper in the long run for me to do this? What other discounts are there? How much is the ap? As you can tell I am totally lost.Any tips/advice would be greatly appreciated.
