Do you recommend the Spirit of Aloha dinner/show? Why or why not? Thanks!!
Your question is a loaded one, but I will try to answer it as honestly as possible.
I would say that the Spirit of Aloha Dinner Show is worth it only if you haven't already been to Hawaii and seen a Luau and if you like that sort of thing(dinner shows). I just saw the show in 2013 after having wanted to for several years. Unfortunately, I went to the Polynesian Cultural Center(PCC) in Hawaii in 2012 and, while I didn't do a luau, saw the dance presentations from the different Polynesian islands. Although Disney bases their dinner show on a birthday party(if I remember correctly), the part where the cast members are doing native dances was very similar to what I had already seen. While it was cute, I was actually kind of bored--but only because I had seen the original in Hawaii.
Check in for the dinner show is hectic. Everyone is basically in the lobby of the Polynesian and you can have your picture taken while you wait to be walked to the venue and then seated. There are three levels of seating and I think you are either seated based on when you checked in or when you made your reservation (don't quote me on that, but I think that's what a CM told me when I made my reservation--I was there very early with some other folks to check-in). I believe I used the deluxe dining plan when I made my reservation(if it wasn't that it was TIW) and was seated in the front maybe two tables back(I believe I was in category 1 or 2 on the main floor). I was to the right of the stage and had a perfect view.
A lot of people don't like luau food, so don't go to the show for the food. I thought it was ok. Everything is served family style and a waiter brings your platters to the table. When you are seated, you already have one platter there. This is what the WDW website says for the food:
"Settle in for platters of authentic dishes, like Island pulled pork, BBQ ribs, roasted chicken and Polynesian rice. You can also savor fresh salad with honey lime vinaigrette, seasonal vegetables and pineapple-coconut bread. Then, polish the meal off by indulging in some warm pineapple bread pudding with caramel sauce!"
I really liked the chicken, salad, bread, and the dessert.
If this is an experience you want to have, I say go for it. You can read reviews of the show on Allears.net under dining reviews.
