I live in suburban Toledo and my thought is...with kids that little, you would have a better time in Cinci at Kings Island. We visit Cedar Point every year and love it. One year we decided to go to Kings Island instead. My oldest two (we didn't take the 3rd and I was pregnant with the 4th) were 8 & 5 at the time. Kings Island has so much more for kids in that age range. While Cedar Point does have Camp Snoopy, its mostly rides for toddler aged kids. Mostly like the little cars that go round and round. Kings Island had twice as many rides for kids to begin with and they were designed for kids a bit older, but not quite old/big enough to ride the "big" rides. Now, my oldest was able to ride many of the regular coasters with my husband because she was tall enough. I even enjoyed riding the kiddy rides with the younger one. They also have a water park that is attached to the park and included with your ticket. Cedar Point has a water park too, but its a separate place requiring a separate ticket. All of the other waterparks mentioned also require their own entry fee, and some require hotel stay (Great Wolf Lodge). On the other hand, Kalahari in Sandusky is a massive resort/water park. You could easily spend 2 days there and never get bored. They have anything from the water park to an adventure course with zip lines and rock walls, to a petting zoo, to a spa/salon. They have a huge arcade, a bowling alley and mini golf course. They also have lots of different food options that are surprisingly reasonably priced compared to other places. If you're looking for the outdoor amusment park, I'd go with Kings Island this year and save Cedar Point until both kids are at least 54" tall (they can both ride every ride at that point). If you'd like the water park idea better, check into Kalahari.
