i too am scared of Everest.
it is one of the thrill rides i havent been on, im also scared to try....
Splash
Big Thunder Mountain
RnR
Mission: Space
and believe it or not still not tried Maelstrom - i heard people scream from the outside last time and i turned around and walked away lol
i am a ride chicken, hate drops and such,
ever since i went on the ToT

with my dad in 2007 and have been a ride chicken.
really want to try these rides above tho and everest just to say ive done everything disney has to do, ive done space mountain and thought nothing of it, just a giant mouse trap ride in the dark lol (not sure if its called mouse trap in the USA)
anyways ill stop hijaking the thread now lol
O.P im with you, i feel your anxiety and i too will be trying this ride in October.
watch some of the videos online about the ride, the drops seem banked drops not direct drops and that can make all the difference in the feel of the ride, ive heard its alot smoother than say space mountain and big thunder as its newer wether that is true or not is a different story
