Hey Jarrod, I go to the induction ceremony every year. As far as signings go most of them you will have to pay. If you go to Mab-celebrity.com they have who is signing and for how much. Jack Berke sports also has signings at the CVS up there. However if you want some free autographs the golf course is a good place to snag some good graphs. That Saturday there is a golf tourny and a lot of Hall of Famers golf. Later in the day there is a parade for the Hall of Famers, they get dropped off at the Hall of Fame. They also sign there but you have to get there early to get a good spot.
With this year being a big year I don't think you will get a hotel anywhere close to Cooperstown. I will be probably sleeping in my car
. Hope this helps.
