Big Thunder Mountain-I just can't work up the bravery to go on it. I was there years ago when the death on it happened. It was fairly new then, and I remember assuring my son about how safe it was, and he rode it and said it felt like you could just fall out because there isn't enough safety restraints, and right after that is when the young man fell out of it. If it had a much better safety restraint bar or seatbelt, I would probably try it.
LizzyS....if you plan on conquering your fear of BTMRR in February, you may be out of luck. Rumor has it that it will be closing for an extended refurb in January and be closed for most of 2013.
I'm a big E-ticket junkie....bring on the rollercoasters and TOT! The drops in POTC and Splash Mtn. are my favorite parts! The only ride I avoid is the teacups. I did them during a trip back in 1998 and felt a little queasy for about an hour afterward.

Not to be judgmental, but there's no legitimate reason to be fearful of safety on BTMRR. This attraction runs every day for 10-16 hours and hundreds of thousands of people ride it every year. The accident that happened a few years back had nothing to do with the safety restraints...the man didn't fall out. The train derailed and even with "better" safety restraints the passengers would have died still. Disney does everything that they can do to ensure the safety of their guests.
And I know it is most likely almost 100% safe. I just like the "feeling" of being more buckled in.
I also don't like the big drop at splash mountain. I've done it three times, I'm over it. I love love love Thunder mountain and will go over and over. I also like Matterhorn. I do wish it wasn't so bumpy. Teacups....forget it, there isn't enough motion sickness pills in the world to get me back on those.Tower of Terror-love the themeing, but afraid of the drops. I hate the feeling of dropping--whether in mid air or in water (like on Splash).
Never been on ToT and I don't think I ever will. Used to LOVE drops like that, but just can't do it anymore. I haven't been on Splash for years because of it. I will probably be talked into it when the kids decide to go on for the first time. We'll see if I ever return. Grizzly River Rapids, because I hate hate HATE getting wet
Mickeys swinging cages of death...or the Funwheel in general.
