We went about a year and a half ago. The food was the best of any dinner show we have attended in Orlando (Disney or non-Disney), and it's a fun show. I didn't know about the unlimited beer part... that's certainly a good perk. Anyhow, it's a good way to finish off a day there.
I been to the Luau at Sea World on April 6, 2007 with my family.
The show was excellent and it is almost the same as the Spirit of Aloha at Disney World. The food was great and even some Luau style too.
Hope to go again with my friends and hopefully to see the holiday version as well.
