You have to switch them to package deals if not already. I was going to do this but CM said that I would have to cancel room only and book package in order to book dining. I was told if within 45 days must pay in full fo whole package. I was told I could add dining to my package up to 48 hours before arrival, but am unsure if I would want to wait till that close. I thought if I had a room only I could pay in full and just switch over to package and apply money, but I was told not the case I would have to cancel receive a refund and rebook, but CM told me that refunds may not be done in a very timely manner. I am no expert but just relating my own experience hope this helped. I was told room only and package reservations are booked in two totally different systems.
