We are going to be on the DxDDP this fall, but we are planning on paying OOP for Via Napoli. We plan on getting a Mezzo Metro pizza (serves 3-5) to share with salads and drinks. We also have a DVC discount of 10%. My expected cost is $70. Even if there was no discount, I would still pay OOP. The reason we don't plan on eating a lot is because we will be there for F&W, so we will fill up on snacks during the afternoon. If you won't be eating anything for a while, you may want to get appetizers and desserts, so then it would probably be worth it to use dining credits.
