Last month we split our stay and used the Meal Plan only at our first resort. 4 Nights at Pop Century, then 5 nights at Saratoga Springs. With sharing I was able to stretch out our family of 4's meals to cover our first 5 days and we had plenty to eat. We were able to use the plan right up until midnight during our first day at Saratoga, then the next few days we just winged it. We were so stuffed from the first 5 days and it was a nice change of pace not to have to stick to the dining plan.
We had purchased the MYW Premium 7 day w/5 pluses. We went to all 4 parks, some twice, both water parks, Disney Quest, and Pleasure Island.
