Hi, I will be visiting my sister who moved to Cleveland 2 years ago. This is my 3rd visit but this time, my grandaughters (8 & 5) will be traveling with me. We will stay for 10 days and want to know of things to do for a granny, or two, and 2 young kids. I know the rafting is not for me, hahaha, but some other activities they might enjoy. Ohh, my dates, the first 2 weeks in July. Thank you sooo very much.
