Being on deck for the trip down the Hudson was very exciting. Don't miss it. Seeing the skyline go by, and then the Statue of Liberty was terrific. We had late seating for dinner in the Britannia so it was not a problem. When we got to the Bridge it was completely fogged in, so we retreated to our cabin to change for dinner.
When you get aboard and to your room, call and make a reservation for dinner in one of the three restaurants that they change the King's Court into at night. There is no buffet casual dining aboard QM2 for dinner. You have to reserve a table for a specific time in the Oriental, beef or Italian section of the King's Court. No jeans etc. They might be able to seat you if you just walk in, but I wouldn't risk it. I'd book a table.
