With 14 day Disney tickets, I wouldn't bother with Genie+ (we haven't bought this). If you do find there is one of the big rides that you can't get on because it is too busy then you might want to just get it for a day.
Eating in the theme parks is very expensive (same as in this country) and...
I'm also heading out mid-October but we have been many times.
To help answer the questions, where are you staying - onsite in Disney, Lake Buena Vista, Kissimmee, International Drive, etc? Also, assuming you have a car to get around.
