How did you know about the Vatican being included?
I noticed that the Vatican was not on their PDF list, yet in some travel magazine article about The Cultivist it was mentioned and included for free, so I called them up and they said that the list is not up to date.
They do cover the Vatican and Maxxi in Rome for free and they can offer concierge for other museums that are not covered.
Here is the email they sent me...
"Thanks for reaching out! It was great speaking with you earlier. To clarify, please see below for the museums we cover in Florence and Rome:
Florence
Palazzo Strozzi
The Uffizi
Rome
Maxxi
The Vatican
For the other art spaces you've requested, we're happy to arrange tickets on your behalf as part of our concierge service. We would just kindly ask to charge your card on file once you have your account set up. Let me know if that makes sense and if you have any other questions at all!"
They also cover many museums for free in Venice.
@Dan - Thanks for my 1st HT! ;-))
