Disney coasters, excluding Expedition everest at the Animal Kingdom and rocking rollercoaster at the Hollywood studios, are seriously tame compared to your normal theme park coaster. That being said, if you are not even into the tamest ones avoid the following attractions.
Space Mountain if open
Big Thunder Mountain railroad
Test track - only if you don’t like speed…this ride is seriously not even what I would call a coaster at all.
Tower of Terror - this is a drop ride, not a coaster, but normally people who don’t enojy coasters, don’t enjoy this.
You can still follow any touring plans there are. Just cross the above attractions off the list and proceed to the next step.
