Well I know that if you book a Candlelight Processional dinner package you must give your credit card information and you are told that you will be billed the full amount unless you cancel at least 2 days prior to your date. We're not doing a Fantasmic dinner package but perhaps they are the same.
CA Grill will bill you $20 each for a no-show. There may be others, but not among the ones I booked.
