OK, Kill the Ryan Air idea (note that web site says total would be about 50 euro - with one bag each). If it is anything like easyJet, I remember that nightmare. I will check JetOne though.
I think we will leave Rome early, do the walk around in Florence, then on to Venice.
Problem with the Italian Rail web site, is that you can only reserve 60 days out. When I check for 10 May (although our trip will be on 30 June), all destinations at VCE read "Mestre." Anyway to check to see if these go on to VSL?
Great advice from everyone, thanks again!
