I had understood that Ventura’s refit would take place in Bremerhaven, but in fact she has sailed to Hamburg and is now (08:00 GMT, 24 Mar) moored alongside the Hamburg Cruise Terminal. Here’s an image grabbed from a Hamburg webcam.

Yes Ventura was refitted in Hamburg, and returned to Southampton on April 06th and left on April 07th for first cruise after refit. P&O’s Arcadia goes to Bremehaven for refit in November 😉
