Laura- sorry I just saw that! Would have been lovely but the in-laws (and DH) don't get Disney or the DIS and would have found it a bit strange.
Just wanted to thank everyone for their wonderful suggestions! We were just there for a quick weekend and I couldn't have imagined I would love Cleveland so much! We stayed downtown and walked to Tower City, Progressive Field (no one mentioned their 8 ft tall Mickey Mouse!) the Rock Hall, Great Lakes Science Center, Goodtimes III river/lakes cruise, and took a cab to melt. Would have loved to spend a week at least, didn't even get to explore
University Circle, Tremont, etc. Firedancer I can see why you love your city! Thank you all!
