Greatly enjoyed our private tour of the Met with Kevin Draper. He was knowledgeable, friendly and enthusiastic, and made our first-time visit to the museum truly enjoyable.
I would note that the tour is geared more towards showing you pieces in the museum that you might not otherwise see when you're fixated on the Rembrandts and the Van Goghs but are incredibly interesting in their own right (e.g. the Faberge eggs that I'm sure we never would have seen on our own). It might not be what a hardcore art enthusiast is looking for, but it's perfect for the general public, especially anyone traveling as a family or group with diverse interests (like we were - parents with teens).
Highly recommended.
