I made reservations for CRT for dinner this August and they do not charge your card..they will if you do not show up..you give them a credit card as a guarantee to some signature restaurants and dinner shows..but they do not charge it! I am on the deluxe dining plan and will use my credits. CRT, HDDR, California grill are just a few that requires a CC guarantee...if you cancel within 48 prior to your ADR they will not charge you.
Even with a party of 11, they will not charge your card.
