DH and I went to both on our honeymoon. It was in January, so both shows were fairly empty (and that may have changed the atmosphere of them), but we didn't enjoy HDDR at all. We're in the minority here, but it just wasn't for us. I totally expected for us to love it, given how cheesy (ahem, Cheesy, with a capital C) my husband is. But we thought the show was overly hokey, and were totally disappointed in the food. We liked the Luau a lot better. While the show was still hokey, I enjoyed the dancing a lot more, and loved the food. I could have eaten nothing but the salad and bread the whole night, they were soooo good! My choice would be the Luau, but like I said, most here seem to like HDDR better. I think you'll be fine either way!
