As DebbieB said, with DVC everything is handled separately. You book your room through Member Services. From there you can add on the Dining Plan, if you wish. The cost is the same as if you go through CRO and you must purchase the plan for all nights of your stay and every member of your party. Tickets can either be purchased through WDW or through a 3rd party vendor. Some DVC members purchase Annual Passes and make a couple of trips (or more!) within a 12-month period. Others buy park hoppers for each trip (or spread them over multiple trips) and others don't do the parks at all. It really is up to you.
