I think the shuttle preshow should help break it up. That one looks and seems more like a ride vs the first and last.I'm excited for this one mostly for tech reasons. Lasers, projection mapping, AI screen portions that follow you as you move around, fast elevator up, simulator/drop down, etc.
But, I kinda get the feeling that by the third preshow this will have felt like a walkthrough attraction to me for 10 to 15 minutes before the ride even starts.While that's cool the first time, I'm sure it will kill re-ride-abily for me a little. I like rides I can just get on and have fun with little to no effort or time spent waiting. Luckily single rider skips all the hoopla at Gringotts, because while it is fun every once in awhile, sometimes I just wanna jump into a quick adventure and then grab a Butterbeer ice cream and be on my way.
I am pretty excited for the music though. It'll be nice to have some fanfare for the land!
