We booked online and paid way too much for our tickets (double the price of a normal entry), good thing was though we went early and just walked straight in, no lining up. David is certainly incredible, I don't think you can comprehend this until you see him for yourself. The museum has some other beautiful works but it is too small for the amount of works that are there and things sort of appear like they have just been chucked into a room. There are so many more incredibly well set out and decorated museums in Italy, they really need to step up there game. My advice, don't book online, go before they open and wait a bit ( the line was not too long when we walked past), otherwise you sort of feel a bit let down.
