Cedar Pointe is by far the best commercial amusement park around. I have been to 4 Six Flags and Adventure Land in IA and Dolly World and Cedar Pointe is the best.
We have also done the whole Disney World thing and I can say my girls enjoyed the theme end of it but not a good park for thrill rides. I would say it is a one time visit when the kids are 7-13 after that not really gonna keep them busy unless they are big into Disney shows
