I've have, in different ways, dealt with all of these.
Last year, Soarin' broke down. Luckily on the last day we reached Epcot in time to hit Soarin' and leave! Mt Everest had the same issue.
It doesn't bother me to much to see other people come in. It makes me actually happy, to see people come excited and happy. The only time it gets me down is at the hotel. (We spend a night at a hotel and then head to the airport in the morning) The feeling at the hotel is just not the atmosphere I want. It's feels so... Not Disney. At least at home, its home, but a Hotel.... feels like we never even went.
Never had to Delay one but my parents can't easily find us going anytime soon. Maybe... Never again. :.(
My time here in Japan has been one of a life time, I could not pass it up. Even though I got a Scholarship, we still forked over 2K, for plane tickets and extra money. To much money for a Disney trip, and now that my sister is off to college, our financial issues are cramped. Hopefully we can go again, or maybe Korea has my name on it. I don't know, but all I know is that the future holds something great.
Here is all I have to say. The company that sent me here wanted all the students to be on a flight together TO Japan, thus a lot of us met in Orlando. Pure torture. I kept joking, "Japan can wait a day, lets got to Disney." I got a couple of mean glances from other students. 0.o Hehe well, it was worth a try.
