I doubt it. They don't charge your CC if you use the regular DDP.... we had ADR's there last year and they DO take your CC info in case you're a no-show. There is a charge for not appearing. They do not charge your CC though when you make your ADR if you tell them you are on the DDP or DxDP.
They ONLY charge your credit card if you are NOT using the dining plan. As mentioned they do take your credit card number, as they will charge a no show fee. Make sure you remember to tell them you are using DDP.
I booked this without the dining plan, and it was charged to my card the week I booked (180 days out) Just to let you know if you plan on doing this OOP. It could be a bit of a shock if you were not expecting them to charge you until you actually dined. I think they do this with the dinner shows too.
