We will be there with free dining for 4 days. I dont know if I should get the refillable mugs for 2 adults and 1 child or not. They are so expensive, but I know my adult daughter will fill her mug several times a day. During our last trip I usually only filled mine at night. My grand daughter will drink maybe 2 mugs filled a day. Free dining gives you a drink with your meals and we could purchase them as a snack. The mugs are great to take home, then again they cost what 13.00 or 14.00 ? How much are they now anyway. I could just get 2 mugs and share with my grand daughter? What do you think would be the best thing to do ?
