I just called Disney dining reservations. Changed my meals around a bit.
I also asked some questions.
1. Can I pay for my friends meals with my credits? yes, you may use them how you want.
2. Are all credits on the room keys and how does that work. Yes, meal credits are on room keys. You only have to have one room key with you to use the credits. Credits will be taken off according to how you order. If you order 2 adult meals and 2 kids meals, those are the credits that will be taken off. If you order 3 adult meals and 1 kids, you will have 3 adult credits and 1 kid taken off. She said the credits are separated according to child and adult.
3. Can you use TS credits for counter service. Yes, you can always downgrade.
4. I told her my son would prefer the adult menu rather than the kids menu, can I not buy him a meal and share mine with him. She said I could, but to check with the restaurant, they may be able to serve him something from the adult menu. That would be up to the individual restaurant.
5. Is the menu different for the fantasmic package than the regular restaurant menu. No, you have the same choices.
6. Are any of the menu's different when you are on the dining plan. No.
