Hi Cierra!
If your family is looking for thrills, here's the rides and parks I suggest:
Dinosaur at Animal Kingdom (I spent this entire ride with my eyes closed!)
Expedition Everest at Animal Kingdom (I spent THIS entire ride with my mouth open!)
Rockin' Roller Coaster at Hollywood Studios {from 0 to 60 in 2.8 seconds)
Tower of Terror at Hollywood Studios (drops 13 stories!)
Indiana Jones Stunt Spectacular (not a ride but there are lots of explosions!)
Mission: Space at Epcot (This one actually made me sick it was so real!)
Test Track at Epcot (see what's it like to be a crash test dummy!)
Soarin' at Epcot (you literally soar over California!)
Some of your littles won't be able to go on these but you can use the
Rider Swap the rest of you can get your thrill quota filled!
Enjoy!
