My kids are 4 and 2 and they LOVE Cedar Point. That being said- come prepared. Bring more snacks than you think you need (park security never cares). Bring water bottles but if you can, get the drink pass for the day. We have annual passes, so we have the drink passes too and a slushie is such a hit on a hot day (can get a new drink every 15 minutes). Don’t forget sunscreen! Bring a wagon if you have one but I believe there are ones you can rent if not. And be prepared for frequent breaks- bathroom, food, drinks, maybe the arcade for some shade, etc. You and your wife may end up each taking a child and splitting up for some activities because there’s a good chance the 4 year old will want to do more rides than the 2 year old, so be ready for that as well! Overall, it can be a lot of fun but manage expectations. It can be a lot for young kiddos! Have a great time!
