I'm sorry it this has been answered before but I was going to make an on-line reservation for two for the Gallery and was not expecting to have to buy the tickets at the same time; I thought I was going to be able to just reserve a time (and pay the reservation fee). We will have a Roma pass so when we go we will pay a reduced rate.
When I went to do this on line it appeared that I had to buy the tickets at the same time. They did indicate that if you had a Roma pass you should call their phone number, but I would rather do it on line. So I canceled out the process.
How do you make an on line reservation when you plan on using a Roma Pass.
