I've been to Cooperstown twice this year, somewhat by chance. I have never been there in summer, though, and I'm told the crowds really do change the nature of this otherwise small town atmosphere. Parking near the HoF museum itself is nearly non-existent, so be prepared to park in one of the satellite lots at the edge of town and ride the shuttle in. (Unless you are staying at one of the hotels in town, but I think they don't let you stay parked past checkout time in their lots.) Those in your party who deeply love baseball will be able to spend the entire day in the museum and not get bored. Depending on your interest, stop inside the HoF Library and chat with the staff there - you could pick up various tidbits if you have any bent toward research and history, however loosely construed. Those who need a change of pace can wander down Main Street after an hour or two in the museum, though most of the shops are baseball themed so those folks may still feel a bit hemmed in. I like the used bookstore on Main Street, Willis Monie Books - they do have an excellent baseball section but there is plenty more in that store for other readers too. Once you wander a couple of blocks south from Main Street, it becomes more like the small town it really is, and maybe will be interesting just for that. There's a surprisingly big regional hospital in that direction, though I doubt it's much of a tourist highlight. The Susquehanna River starts at the southern tip of Lake Otsego, just east of downtown, and I recall statues and other memorabilia regarding the Revolutionary War - a patriot general intentionally breached the dam that used to be there. The lake itself is a vacationer's destination in its own right, so one alternative would be for the baseball junkies to spend the day at the museum and the others drive north a few miles on the east side of the lake to Glimmerglass State Park . On the west side of the lake is the Glimmerglass Opera, which is supposedly good although opera's not my thing, if you're looking for an evening activity. The Otesaga Resort Hotel in Cooperstown is a grand old place harkening back to the Gilded Age and might be a worthwhile few minutes of looking around. Miniature golf seems to be a very big thing in the area, in season, due no doubt to the number of families passing through. My guess is that getting meals in the area will be time-consuming for you due to the crowds. We had a very good meal at Council Rock Brewery back in May, except we sat through a 90 minute wait because the staff failed to mention they had a large party in the back and the kitchen couldn't keep up. If it's like that in the shoulder season, I suspect you'll find that kind of treatment everywhere - just plan to roll with the punches and consider it part of the local color. But the HoF and museum itself? Just go!
