Samantha,
You didn't say the in-laws were paying! When should I be there?
Seriously, here are four recommendations at non-park dining locations throughout Walt Disney World, by both expensive and moderate pricing;
Expensive
- California Grill (Contemporary Resort - great views even better food from the top floor of this iconic resort)
- Jiko (Animal Kingdom Lodge - Wonderful private room that is perfect for your group size, and exceptional food, both exotic and not)
Moderate - The Wave (Contemporary Resort - great food and nice atmosphere, just no view)
- Wolfgang Puck Cafe (Downtown Disney - a nice mix of food choices, and an easy to get to destination)
Without question, a table at California Grill would be ideal. Your view would probably not be of the Magic Kingdom (and it's eventual fireworks display that night!), but the view is still spectacular. And your guests could venture over to the outdoor terrace off of the main room to watch them, cocktail or dessert in hand! A real treat. As for Jiko, I was treated to a private meal there in December, and the setting and food were MARVELOUS!
I am glad to answer more questions! Yours are fun to answer!
Have a magical (and delicious) (and romantic!) vacation!
