I want to go ovrnight from Rome to Milan on May 24 and found a non-stop train that leaves Termini at 22:40 and arrives in Milan at 6:25. This train would be perfect, but when I click to buy the ticket the ticket choices that show up are priced at 46 and 30 Euros for first and second class respectively. There’s no option for any kind of sleeper and so I’m wondering if this means a) sleepers are all booked, b) there are no sleepers on this train, c) these are the cheapest sleepers around. I found these fares on the trenitalia website, and am wondering if there’s another site I can check that will poosts both schedules and prices.
