Sorry to hear you had to cancel your trip. I understand and sympathize. We booked for next week about a year ago. I have been anxiously awaiting. About a month ago we decided we needed to cancel due to our current financial situation, and it was not a good time to take kids out of school. It makes me sad every time I see a WDW commercial on TV. But....I am focusing my energy on a May 2014 trip. It seems like a long way off, but as a PP said. 2014 should be a better year to visit WDW. FP+ (like it or not) should be implemented and hopefully the bugs worked out in 2013. I am hoping New Fantasyland (including the mine train coaster) will be complete by May 2014. Also the Polynesian, our favorite resort, is getting renovated in 2013.
So, I understand your pain. I am an optimist and I believe that WDW will be even better in 2014 than it is today. Try not to focus on what you are missing out on this year, and focus on your next trip to WDW. As PP mentioned, start saving now for your next trip. Every penny you can put away in 2013 is that much less that comes out of your pocket in 2014.
