Below is a practical, sightseeing-focused plan that keeps a safety buffer before every all-aboard time. I’m assuming:

Brussels port = Zeebrugge
Paris port = Le Havre
The ports are visited in the order listed
You'll use taxis, trains, or ship-organized transfers where necessary

Aim to be back at the port at least 60-90 minutes before departure-especially on independent excursions.

Best choices if you want to reduce rushing

Hamburg: Speicherstadt, Miniatur Wunderland, and the harbor.
Copenhagen: Nyhavn, Amalienborg, Rosenborg, and the Little Mermaid.
Skagen: Grenen and Skagen Museum.
Oslo: Vigeland Park, the Fram Museum, and the waterfront.
Rotterdam: Markthal, Cube Houses, Erasmus Bridge, and Delfshaven.
Brussels: Grand Place and the historic center only.
Paris: Eiffel Tower, Seine, and a few central landmarks rather than attempting many museums.

Brussels and Paris are the most logistically demanding days. From Zeebrugge, Brussels is roughly a lengthy transfer each way; from Le Havre, central Paris is several hours round trip. For both, a cruise-line excursion or prearranged private transfer is preferable to relying on multiple independent connections.
