We are first time Dvc members going to Disney this July. Can I add the dining plan a week before? I heard somethiong about a fee. Also, can I buy tickets there, or should we add them before we go? Thanks!
You can't add tickets through Member Services, like a Disney package. You can purchase tickets when you get there, either at the resort or the parks. But many purchase tickets in advance from a discounted reseller (Undercover Tourist most frequently recommended here, with an additional discount you can get by subscribing to Mousesavers monthly newsletter).
