Hi Traci,
A six-night stay in a two-bedroom villa at Bay Lake Tower at Disney's Contemporary Resort sounds absolutely wonderful! It is such a great resort. Be sure to check out the fun at Bay Cove Pool, and enjoy the walking distance to Magic Kingdom.
I checked with Disney Vacation Club Member Services, and the answer to your question is yes. Once the members of your party who are only staying a few nights depart, those of you who are still at Walt Disney World can continue to use their dining entitlements. The dining entitlements should all be available on your Key to the World cards.
This sounds like an excellent reason to try some meals that require two table-service credits! These include Character Dining, Signature Restaurants, and Dinner Shows. From these categories, I really enjoy Cinderella's Royal Table at Magic Kingdom, Citricos at Disney's Grand Floridian Resort and Spa, and the Hoop-Dee-Doo Musical Revue at Disney's Fort Wilderness Resort and Campground. For a full list of restaurants which participate in the Disney Dining Plan, as well as which require two table-service credits, visit the
Disney Dining Plan information website online. You can click on documents on the right-hand side of that website which will give you brochures for the Disney Dining Plan.
However you decide to use those dining entitlements, Traci, have a great time on your trip! Please do not hesitate to ask if you have any further questions.
