If my family of 4 gets the dining plan and my in-laws use their Table in Wonder discount, can we all go to dinner together at a table service restaurant and sit together? Someone told me that all members of the dining party needed to be on the dining plan... Can we pay for our's with our dining plan and they pay for their's with their Table in Wonder discount and cash/credit card? Thanks. I'm new to the dining plan and still hoping for free dining this spring...
