Disney may lose in that situation but so does anyone else who wanted that room and was willing to commit to it. I think the biggest philosophical difference in this debate is the idea that is it or is it not appropriate to tie up space that you are not committed to using. This debate is the same as the one about people making multiple PS for the same time without planning on using both or one person reserving spots for many other people at a key parade viewing spot. Some people think its OK to do it and others don't. Personally I would not feel fair tying up a reservation and potentially blocking some one else just because I was not able to make a decision about what I wanted to do regardless of the reason.
So happy that it all worked out for you. Have a wonderful trip!
Am so glad you got Disney to fix the problem and have a GREAT trip!!
