Hi Autumn!
Welcome to the Disney Parks Moms Panel. It sounds like you are going to have the most magical 30th birthday celebration possible. I also spent my big 30th birthday at the Most Magical Place on Earth and I had so much fun. It took the sting out of not being in my twenties anymore a little easier to bear. Enjoy every minute of your vacation.
Since you are going with such a large party, I highly suggest
'Ohana as a birthday meal your whole family can enjoy together. This all-you-care-to-enjoy feast is filled with delicious food and fun. You will be able to enjoy skewers of shrimp, chicken and steak as well as dumplings, noodles and veggies. During your meal the children in your party will be entertained with singing, and even coconut races. For the adults 21 and over you can indulge in some of my favorite Disney cocktails on property. The Lapu Lapu and Backscratcher are Disney must-dos , and will not disappoint. 'Ohana means family and you will feel right at home at this welcoming Disney Dining establishment.
I encourage you to give 'Ohana a try, I know you will fall in love with it just as my family has. I wish you a very magical birthday celebration and please stop by again with any other questions you might have.
Aloha,
~Jen
