Is a reservation needed.

Our tickets were good for 2 days. Reservation on the first day the ticket said you can come back on the second day as you wish. I hope that helps. The museum is amazing

Thank you for your inquiry regarding a possible visit to the Corning Museum of Glass. We request a reservation be made to visit the museum because tickets sell out due to being at maximum capacity at the museum. If we have availability, we will sell tickets to walk in guests, however rainy days and peak times fill up quickly.

I would recommend advance purchase but there's no harm in trying. The day I went was a weekday and not real busy.

No... Reservations are not necessary.... Tickets are available on the location
