We are going to all the parks this November. Our 4 year old will be tall enough for some rides like Space Mountain. I do not care much for rollers coasters but my other son and husband do. I do not believe our 4 year old is old enough to endure a thrill ride such as this one. He has never even been on Slinky Dog or other smaller ones because we have not been to the parks in 2 years. Our families are on different sides of the fence: I think we should start him off on the kiddie ones first and see how he reacts. The other side thinks that if he’s tall enough, why not let him? Please chime in…
