Really love ToT, as does my daughter. My son, on the other hand, who will ride any roller coaster and Mission Space (which put me out of action for the day), hates the ride and refuses to ride any more. Last time we road a young couple sitting next to me screamed the entire time. But yeah, the ride is awesome. I don't like heights at all but never really notice them. And it isn't super dark, but in any event I'm not sure a glow stick would be appropriate (but also not sure that anyone would really notice during the drop, just don't use it during the pre-drop part).
