Yes, you should make a reservation for CRT if you can for the date that you want. This restaurant is very popular so you more than likely would not be able to walk up. You do not have to pay out of pocket, when you are on the dining plan but remember it counts as 2 table services. But since you are on the deluxe that is even better. When making a reservation for this restaurant you will have to give your credit card to hold your reservation only. It will only be charged if you do not show.
