I would suggest taking the ferry to Kellys Island rent a golf cart early in the morning 10am not sure when they sell out but in the summer it could be quick. Its very laid back just drive around for the hours you rent the cart.
We went with 4 little girls & 4 adults and rode around all day, went to the beach collected shells, the huge quarry we used to swim in the 80's now off limits - a little hike to get to but its huge, go see the glacier grooves, bought squirt guns and filled them up at bathrooms restaurants and had a blast, singing songs loudly. Wave to each person we passed everyone was so nice.
Probably the best fun we ever had together. If someones hat or sunglasses blew off and we stopped to let that person go get it as soon as they got off and walked a few steps my one cousin would take off, then backed up to let whomever on. This went on all day. We were peeing our pants over that.
Here is a glacier groove's while i'm at it
At Put in Bay I would worry about the drunks on the roads, my DH was t-boned near downtown and the car he was in was totaled out, hit by a drunkdriver. Its a party island for sure, think mardi gras I cant even recall how many people were flashing there goodies in the bars eww.
We've also taken our nephew who was 7 at the time. Went to a cave, perry's monument, drove around, i think they have a area to pan for gems near the cave. Didnt have alot of fun but thats because i was there with my husband and his parents
