Hi Maureen,
First of all, congratulations a little early to your son and a very happy birthday to your father! What a special place to celebrate these amazing milestones as a family. I wish both of them the ultimate happiness and treasured family memories of this celebration.
Several years ago, I traveled with my family and some friends. All together, we were 17 people and we were able to comfortably gather in several locations.
- Chef Mickey's at Disney's Contemporary Resort
- Biergarten in Germany at Epcot
- 'Ohana at Disney's Polynesian Resort
I have also seen large parties at many other locations.
- Whispering Canyon Cafe in Disney's Wilderness Lodge
- Boma - Flavors of Africa in Disney's Animal Kingdom Lodge
Based on all of these restaurants, my biggest recommendation for the two special guys you will be celebrating would be Biergarten. It is unique with its Bavarian performers, the service is awesome, and the food is hearty and quite delicious! It is actually some place that we go on every single family trip.
Keep in mind that in some of these locations you may be broken up into several tables. Also, be sure to book your reservations up to 180 days out since many places will book up very quickly and with a party this size, you want to be sure to get the best options.
Happy planning!
