We recently completed a Uniworld Cruise (Castles Along the Rhine) on the ship, SS Antoinette from Basel to Amsterdam (09.25.22 to 10.02.22 with a post-cruise extension for all in Amsterdam until 10.04.22). two (2) Parents (us), two (2) Adult children with spouses for a total of six (6) guests.
We as parents paid for all the costs including air from Uniworld Air Dept, Uniworld Insurance, and excursions. A substantial cost to say the least: around $75K. No small sum.
