Okay, I am a person that doesn't do drops (ToT =

So does Splash Mountain) I HATE drops.
That being said... My heart was about to beat out of my chest because, I've been afraid of rides since I was a kid. I got over my fear of Space Mountain last year and have been a little braver so, we hopped on EE just after rope drop.
It's SUPER smooth! Right out of the gate it takes off with a bit of pep, the climb to the top is really smooth and silent since Disney spent mulah to not have the ride do that "click-click" sound that most chained coasters have. I LOVED the backwards part! It basically goes backwards, at an angle and twists down (see: helix). It does not go upside down nor did I feel like I was going upside down. I didn't get a headache or anything like that. But, because I tend to be a nervous nelly, I did have a motion sickness pill.
The drop... me no like but then, it was my first ride. I hoping to get back on when we go back this year. I think the drop scared me more than gave me that "bottom out" feeling. After the drop the coaster flies in and out of the mountain which is a wonderful feeling. It's much than SM and BTMRR (Neither of which do more than 30MPH - EE does 50mph).. and is themed so much better than both with a few surprises.
BTMRR is my fav though, I always ride that one several times.
