As a 44-year old father of 3 kids between 8 and 13, I think a "family" (not kiddie) coaster would be perfect in Jurassic Park. I love hyper-coasters as much as the next guy, but the older I get, the more I distiguish between "thrilling" coasters and "fun" coasters. Hulk and Dragons are both great and definitely a "thrill" - but when I get off them, I'm glad they are over. The kids might want another go, but I'm looking for a bench, and a beer, and a break. "Family" coasters, like Big Thunder Mountain, for example, I could ride a few times in a row, with the kids and wife in tow. And we all love it.
So I say a FUN, 3-to-4 minute long, heavily-themed, semi-thrilling, just-a-lapbar, sit-three-across-with-my-kids-if-I-want-to, Thunder Mountain-style coaster that I can ride over and over again with my whole family is just what IOA needs.
