Very good points. I booked two inside cabins for the 15 day Panama Canal trip in July. I have been on alot of lines and NCL is a good product for the price. The Norway was a great ship.
You are starting to see more main dining room choices. Both HAL and Princess ofer 5:45 -8:30 stager dining times. Both it's not Free Style and some of the higher end lines offer opening seating all the time.
If you could give me some specific advice on the Sea it would be great.
