Has anyone used tickitaly.com to book tours and reservations to these sites?
No need to book Pompeii tickets ahead of time, you can just pick up tours right in the main gate as well. The Last Supper is another story, I would try the official site first though since most companies add fees of one sort or another.
I just bought my Last Supper tickets on tickitaly.com for our trip in October. I am only in Milan for a day and was getting nervous that I couldn't find any online tickets for October 2. Got 'em now!
I used tickitaly last year for Last Supper tickets. Would use them again
