Sorry you are having trouble. Regarding the FP+ for lunch, if you are using the MDE app, go online with your computer to the special website for BOG lunch FP+.

I did not have to put in my reservation, just sign in with my Disney account email address and password. But I am within 60 days of arrival. AFAIK, there are no FP+ available for December dates yet. The late November dates for this just became available this morning. Good luck!
Yeah, I've tried that link several times and all I get is an error message. I would have been happy to settle for lunch... If this doesn't pan out we are still planning on waiting in a long line for lunch. Though making this reservation would be much more magical ^_^
