My Husband and 21 year old daughter are coming to Venice Mar.21 for a few days. I have been trying to go directly to the museum site to buy tickets. Fri night I got on hitting a link from one of these posts and was part way through the booking and I had to leave. Now when I go back to try to do it( I don't want to have to pay a booking fee through a tour co.)some tech company comes up with that web address. I even went to the Venice tourist board and it's link goes to this random site. What happened?
