I rode the ride at WDW which I know is a little different, but I hated it. I have a huge fear of heights. I can't even ride the ferris wheel at our local amuzement park - my heart rate speeds up and I can't breath while I'm at the peak. I think you'll have a lot of fun if you aren't afraid of being high. Good luck!!
This is interesting... I seem to have a fear of heights too, and yet, read on...
I found out last week that I really don't care for the Sun Wheel - we rode it at night, and it stopped a lot near the top (I think I thought we were getting stuck, LOL) and I felt so sick/scared/queasy the entire time. I had no clue I would feel so queasy on a ride. I do know that I was thinking... "What if this falls down, what if it tips over?"
For some reason though, despite being able to only go 3 or 4 steps up a ladder without getting queasy, and despite the new found fear of the Sun Wheel, (that was my first time to ride that ride) I can ride California Screamin' and love it - I can ride the maliboomer, and think it's great. The tower of terror, the same thing. I can also ride splash mountain no problem. So even if you do think you are afraid of heights, you never know, you may be able to deal really well with this type of ride. And because you are enclosed, it feels almost better than the jumpin' jellyfish ride, which, I also find makes me feel a bit queasy, LOL!
Our 5 year old rode the TOT once, and liked it, but did not like it at all when they say 'Wave goodbye....' even though she knew it was all fake, it was still a little too spooky for her, and understandably so.
I think you should try it, OP... everyone in our family (all 4 of us) generally liked the cool tummy ticking feel. I also have to add, it does NOT feel like an elevator dropping out from beneath you - somehow, it feels nice and controlled, not the way one would imagine a real elevator falling down unexpectedly. The only thing we didn't like??
The ***SCREAMERS*** - It hurt our ears so much! It isn't scary enough to scream about. It's not bad at all. If you try it, please post your thoughts on the ride, we'd love to hear.
GOOD LUCK!!!!
New edit - one more thing - day 1 at the parks, we felt every dip, drop, curve, turn and swirl on every ride, in the pit of our stomaches. By day 3 or 4, I felt a noticeable difference in my ability to go with the flow, LOL. Suddenly, I didn't feel lurching in my stomache as we dipped down in the PotC ride, nor for some of the dips on BTMR or on Splash Mountain (the dips, not the big drop, I mean.) So... if you get a day or two in first, to 'condition' yourself, it might help - on the other hand, I was afraid to go on the Maliboomer and California Screamin' for the first time, so I did the old 'just walk on in and don't think about it' trick, as soon as we saw the rides. I didn't stop to look at them. I was afraid and nervous, to be sure, but because I had taken myself by complete surprise, it worked for me, and I didn't have to worry and fret about what the ride might be like. I think everyone should try it once, at least...
Her response... "thanks guys. Now I'm pretty sure I will never go in another elevator again in my life!" 
Actually, I think she kind of enjoyed the thrill, but because it was in an "elevator" that made it fearful for her. Not to worry though, she's still my friend! 
I adored it!!! I was very nervous, and still feeling a little skull-rattled from screamin', but went anyway and thought it was a fantastic ride. I was shrieking like a 4 year old myself....sooooo fun!!
. PS: The back is the best cause you can put your feet up and scrunch your self up that way your tummy dosent feel all knotted up. Hoped this helped and by the way if you do go on make sure 2 SMILE!!!!!!!!!!!!!!!!
