Hi, Janey!
For a memorable dining experience to cap off your visit, I would recommend the
California Grill at Disney's Contemporary Resort,
Narcoossee's at Disney's Grand Floridian Resort & Spa or
Artist Point at Disney's Wilderness Lodge. From both California Grill and Narcoossee's, you can enjoy a wonderful view of the Wishes fireworks show either from your table or from out on the roof overlook or wrap-around porch, respectively. This would certainly be a magical finale to the last full day of your vacation! Artist Point also offers a signature dining experience in the lovely setting of Wilderness Lodge and tends to be a bit quieter and more relaxing. Any of these three dining locations would be a great choice!
Since you are less than one month out from your arrival, it may be difficult to secure a reservation for these sought-after restaurants. I suggest checking the
online Dining Reservations page or calling 407-WDW-DINE as soon as possible to check on availability for dinner on November 17. There are also several good alternatives in Downtown Disney -- two of my favorites are Wolfgang Puck Grand Cafe and Raglan Road Irish Pub & Restaurant.
Please send me a follow-up question if you'd like more details on any of the suggested restaurants I've listed or if you'd like other options.
Wishing you a magical vacation!
