wwyd Dreams Park/Induction weekend - Oneonta or in town?

I am wondering which avenue to take - son and hubby are doing Dreams Park, which begins induction weekend. They, of course, are in 7th heaven. Teen daughter and I are coming (for at least part of the week; not sure how much to do as we are not hugely into baseball). What works best? We have options for staying at a chain close to Dreams Park (very pricey!) or down the road in Oneonta, which right now is our plan. Does being able to retreat from the craziness of Cooperstown during induction mean we won't be able to get into town due to traffic?
