I highly recommend using their shuttle service to/from the luau. The shuttle guide allows you to mingle with the other attendee's, which makes the whole experience a lot more fun and interactive.
The experience as a whole was excellent. I went with two friends and had a blast. Dinner was delicious and had a good variety of options. I don't eat fish but was full off of kalua pork and chicken. The noodles, bread and desserts were excellent too.
The show was great! The chief that MC'ed our show was HILARIOUS. My stomach was sore the next day from laughing so hard all night. The dancing, interaction, fire dancing, and cultural education was great.
Honestly, if you're looking for a good time for any age, Chief's Luau is the way to go! Bring a jacket as it gets pretty windy and enjoy your time with them!
