None of the above, but I am a self admitted adreline junkie, with roller coasters being my vice of choice

I have to be riding that stuff all day straight before I start to feel anything. At which point I get something to eat, rehydrate, and then ride some more

But of course that's me.
If I were geuss what would make some of the more motion sickness prone DISers quisy, Tea Cups, Star Tours/Body Wars (you don't really move, yet it looks like you do, throws off equillibrium). I would also geuss that Primeval Whirl and Soarin would also make some people sick, but I havn't been on those so I honestly don't know. (Primeval Whirl is of similar principal to the tea cups, and as I understand Soarin is similar to motion simulators in that the scenery moves, but you really don't) Everything I've heard about Mission:Space is not good for someone who has a weak stomach. I am REALLY looking forward to experiencing it, but please see my first paragraph

Good luck with your riding experiences. Best advice is to know your limits and not overdo things. If you get to feeling sick, sit down and rest. Shade and H2O are your friends. Believe it or, but I find that food helps to settle me down too, particularly things like pretzels, french fries, or ice cream (no, not all at one sitting)
