Do it! Yes, the price tag is high.....and it is worth every penny! To have the MET to yourself with a very knowledgeable museum curator has set the bar high for all future museum visits. I wish they offered this type of tour of more museums, as we would sign up for nothing else but this set-up to truly be able to enjoy the space and the artifacts while getting insight beyond what is on the label and yet without the crush of the crowds.
Not cheap, but well worth the money. To see the MMoA ahead of the crowds with a personal guide is something amazing. From being able to clearly hear your guides and close up views of exhibits, through to being able to take photos of completely empty rooms - an amazing experience. And, just as we finished up the front doors opened and floods of people came in. So glad we saw the museum this way and now think it may be the only way to visit museums!
The empty space was a privilege. A small group of around 25 of us were alone in the Met for an hour and a half before the doors opened at 10am. We drifted past barriers reserved for later lines who would need to queue to get into the Temple of Dendur or even the cafe. When our early-morning tour was over, we had access to everything else. So you can see what you want to see, after your tour, yet cherish the knowledge that you've seen it without the crowds getting in between you and the picture or sculpture. Much recommended.
