While booking a Milan to Naples ticket on the Italo high-speed train, I noticed some nice fares. Even the highest class, "Club Executive", has seats priced at €49 for a full fare on this stretch.
On the side, there is a "Salotto" option, which seems to be the same seat but in an enclosed compartment. Maybe there is some additional service, but there is something not clear. And it costs €200.
How can the price of the seat in "Salotto" be four times as much the price of an identical seat in the same class with the same ticket flexibility? Some less flexibly-priced regular Club seats are worth €29.
Does the high price justify special service, or is it simply that buying a single "Salotto" ticket gets all four seats in the compartment?
