Hi Michele,
Thank you so much for visiting the Disney Parks Moms Panel with your question. Bay Lake Tower at Disney's Contemporary Resort is one of my family's favorite Disney Vacation Club resorts. We love the sleek and modern feel, and the walking distance to Magic Kingdom is so convenient!
Disney's Spirit of Aloha Dinner Show at Disney's Polynesian Village Resort is a fun show. The luau dining and the entertainment are very enjoyable, especially when going with a slightly larger group as you are. We attended this show recently, and my husband was called up to dance with the cast members, much to the delight of everyone in our traveling party!
If you are looking for a dinner show at Walt Disney World, I would like to recommend also
Hoop-Dee-Doo Musical Revue, a foot-stomping, hoot-hollering good time at Disney's Fort Wilderness Resort & Campground. At this show, you dine on fare like fried chicken and strawberry shortcake during rollicking fun entertainment. My husband also got called up on stage for a part in this show!
Both of these dinner shows do require two table service dining credits. From Bay Lake Tower at Disney's Contemporary Resort, getting to either of these shows will be fun and easy. To head to Disney's Spirit of Aloha Dinner at Disney's Polynesian Village Resort, you can hop on the monorail. To get to Hoop-Dee-Doo Musical Revue at Disney's Fort Wilderness Resort & Campground, you can take a boat.
I hope that these thoughts are helpful for you, Michele! Have a wonderful time planning your vacation, and please do let us know if you have any further questions.
