It was the only way that I considered seeing RoL. I am not a fan of AK. I think they hit the African theming just right - because I when I am there I think I feel just as I would in the real Africa - it's hot, boring and I want out!
We did the dining package (Tusker House) in March when it was just me and one of my daughters. We spent the extra time in between the meal and the show at the air conditioned bar attached to Tiffins. We did almost the same thing in May when it was me, my husband and my other daughter (our reservation was a bit later - so there was no bar time). I only went the second time because my husband didn't want to go alone.
I would say - that for me - it is the only way to do RoL. I would not block out an entire day of Fast Passes for it. I don't want to do anything else in that park.
I don't think there are any bad seats in the viewing area. We walked up around 15 minutes before the show on both of the nights we saw it. It was definitely the way to go for me. Money well spent.
Before these two trips, the last time that I went to AK was 18 years ago. We have been to Disney World over 20 times during those 18 years. I plan on possibly going back to AK in another 18 years.
