That's actually pretty cool about that wall in AK and being the heads of Scar and Simba. I bet they do those sort of things to a) be cool for guest but also b) for the workers to entertain themselves
Bummer about your meal and taking so long. Sounds like everyone handled it properly - you were definitely in the right to complain as you noted something specific that wasn't working right and you calmly explained as such to customer service who calmly agreed with you and tried to make it right via ice cream and fast passes.
I don't know why you bothered to go on EE again as your bonus fast pass right ... you and Amber look downright board in your ride photo!
We've never been to WPE (I know, bad DISer) but only hear good things about it. Those pizza's look great!
