The refillable mug is included in the Disney Dining Plan(DDP), which comes in very handy for your length of stay, which can be used at all resorts, not in the park. Comes in handy for coffee in the morning and soft drinks at the pool etc. If you are a coffee drinker like me, coffee can become expensive buying out of pocket. Signature Restaurants take 2 Table Service Credits, but there are many restaurants that take 1 Dining Credit. Many of the popular restaurants are filled with advance dining reservations quickly,(ADR), so do make your ADR's at 180 days. I know that sounds crazy to plan where you are eating 6 months in advance, but that is the system if you want the more popular restaurants. We usually do the DDP and usually do 1 Signature Dinner during our stay. We therefore pay OOP for 1 dinner meal, or eat something "on the run" at the parks. The Signature Restaurants are usually very good. When it is just my husband and I traveling, we are not big break breakfast eaters, so oftentimes, we will use 1 Snack Credit in the morning for a pastry or muffin. The DDP usually works well for us. Enjoy!
