My mom always hated drop rides, but rode Splash and ToT anyway because she enjoyed the story lines. The day she had her gall bladder removed, as soon as she was discharged from the hospital we headed straight to WDW (can you tell we're addicts LOL). She loves roller coasters but opted to skip them that day (naturally). But she went on Splash... said it didn't bother her at all, and this was literally 6 hours post-op. So you should be fine, the drop really does look a lot worse than it is. Like others have said, there are several smaller drops to prepare you, and the big drop is just fun, not anything like the ToT drops. Have fun!!
