OK - I know I sound like a total snob here, but we all have different preferences. Each to their own etc.
Many years ago I went on a P&O cruise. HUGE ship rammed to the gills with thousands of people. Casinos everywhere. Food, food, food, food, food. Booze, booze, booze. Swirly carpets. Bling and showy. Shit entertainment from yesteryear. Hated it.
Maybe it's changed since then but the experience I had put me off big time, especially at the price of it. But I like the idea of cruising. I want something smaller, I am interested in more cultural / intellectual stuff. Not into the bling and the lights. Does such a thing exist?
