The new Queen Elizabeth. h/t, Theo.
She has the hull of a liner, but the superstructure of a Miami Beach hotel. Everything is quite elegant inside, but on ships like this you can too easily forget that you are on a ship at sea.
I prefer smaller ships, like many of the Holland-American line, that feel like big boats instead of like giant hotel-resorts.
Call me a snob if you want to. I like the Ryndam, below. I was looking at her because we need somewhere new to go to in 2011 - and I love ships 'n boats.
