We had Thanksgiving dinner last year at Boma at the Animal Kingdom Lodge. It was SO good!!!! I know it's not convenient to the Boardwalk Inn, but it is worth it in my opinion! The resort has animals ON-SITE that you can watch roam around in their savannahs (giraffes, zebras, etc..), outdoor fireplaces with storytelling, the resort itself is just gorgeous!
Boma was a wonderful dinner. Not crowded at all, a yummy traditional Thanksgiving feast, african dishes, amazing soups and salads, and amazing desserts!!
