We just returned from a 4 day trip to NYC. Tried to book as many inexpensive or free attractions as possible. The federal reserve is an excellent option. Unfortunately we could not score any tickets for a guided tour that included the tour of the vault. Instead, we settled for the self guided tour and while interesting, it was a bit sparse. Likely, related to the fact that the coin exhibit is no longer available. Hopefully, they will enhance the attractions. There are no photos allowed, and make sure you bring your tickets and ID or you will be denied any access. You also need to go through security screening as well.
