This Smith's Family Luau is the ultimate luau experience. I recommend the Fern Grotto Cruise at 3:30pm for just $15 -- it will take you back to the park at 5pm when the luau grounds open. Make sure to park by the luau and walk to the cruise. You will walk the beautiful garden park before the luau begins. Purchase the bird seed for $.50 and watch everything from chickens to peacocks follow you.
The Imu ceremony starts at 7pm, followed by the dinner. It is all you can eat and drink for one price: $58. Most luaus limit the number of drinks or do not include an open bar, unlike this one. The luau show is fantastic with volcano eruptions and dancers from all over the islands. It is also performed at an ampitheater, so no seat is a bad seat.
