Just a note to tell all of you who find the Trenitalia site impossible, that there is hope. I finally got reservations. There is joy in Mudville!

As I mentioned above, the damned site would not accept any of my credit cards. I was able to register successfully by turning off my pop up blocker, but it would not admit I had any credit, even though my card companies said my card was fine, and that no charges had been submitted.

I was beginning to believe that they should change the name of the site to, "Abandon Hope, All who Enter Here!"

I the end, I cheated. I used my wife's Mac computer, and the system worked like a charm. I now have tickets for my party of three from Rome to Firenze, and from Firenze to Venice.

Go figure===

nukesafe, I suspect they only allow one or two online purchases a day, and you got the lucky number that day.

We ended up purchasing our ticket from a travel agency office in Florence the day before our train trip. Just walked into an office we found on the street and they only charged 3 Euro to buy and print the ticket for us (in cash).

I completed three online ticket purchases successively on the Trenitalia site. So I don't think there is a limit.
