Scott, I am so sorry to hear that you're not feeling well again. I know it's a difficult decision whether or not to cancel. However, you don't want to waste a Disney vacation if you're not ok! You can always go another time. The way it sounds, you're good one day & then really bad the next. Couple that with the storms lurking out there, perhaps it would be better to "delay" the vacation. You could add days onto your October trip or add a December get-away!!! Disney is beautiful around the Holidays!!! We can all give you suggestions, but ONLY YOU know how you feel!
