No you’re wrong, raising your hands does nothing! Everyone knows the only way to make a coaster go faster is to row up the lift. There is no current method for increasing the speed on a launch coaster.
Matterhorn has two successors that are better, ride wise (but not theme wise) MK Space Mtn is a better more thrilling version of that ride system, and Everest in terms of theming. Alice wins for me, my favorite Fantasyland style dark ride.
2014-2015. I got normal DL for half my AP and 60th anniversary DL for the other half. That meant I got Halloween Screams, Believe, Remember and DL Forever.
If we are restricting it to DL and times I’ve visited, the year I had an AP from Oct 2014-Oct 2015 would be my choice for sure. Halloween party still at DL, get to watch Remember Dreams Comes True and DL Forever, 60th anniversary, get to see regular WOC for some of the year.
