If you did not already have a reservation with a dining plan added booked before October 14, 2010, you have to pay in full for the plan at the time you add it to the reservation.
If you made a reservation WITH a dining plan before October 14, you pay at check-in. If you had a reservation booked before October 14 but you add the dining plan after October 14, you must pay for the plan at the time you add it. The check-in payment applies ONLY to reservations that had a dining plan added before October 14.
If you want to wait to pay for the plan, you can call Member Services up to 48 hours before your arrival date and pay it then. But no more paying at check-in. The latest you will be able to pay for dining is 48 hours before the arrival date.
The new rule is making it difficult on renters, who now have to arrange DDP payment with the member they are renting from, because only the member can call MS to add the plan to the reservation.
