This is under consideration for a charter. Been that way for quite a while so I think it is going to be a charter.

If it is chartered I will probably do one of these two sailings below. There are some new ports. I want a Prestige sailing around this time.

June 8 - June 26, 2027 - 18 nights. Lisbon to Rome. Some some new ports as well. (copy the link)

Or the second half of this cruise
June 17 - June 26, 2027 - 9 nights.

I think 9 nights is too short for travelling to Europe so I will probably go with the full sailing of 18 nights.
