My husband and I love taking our kids places that are not only fun but do have some educational value to them. Not that we never do anything just for fun...but COSI is a place that both of us went to as children and wanted to share it with them. We are now totally addicted! We bought 2 year memberships! You can go whenever you want for free, you get emails or mail about special members only things going on with the Museum also. You also get 20% off in the gift shop. IF you live anywhere near COSI, we live in Ashland, Ky and drive approx. 3 hours to Columbus, but it is so worth it. When we have school breaks we go, and end up only needing about $150 for gas and food. Then $25 when we get there to get into all the extra spots in the museum.
If you can get to COSI and have never been, you need to go! It is an amazing and fun place to take your family!
