I would really like to stay in the underground one, or the Norway one, mostly for Norway (and I love communal saunas). The one in India looks fantastically beautiful too, and the one in Kenya. If I stayed at the Icelandic one I'd imagine I had died and gone to Valhalla, to wait for the final, glorious, hopeless battle. And I would drink a lot and be very uncouth. Huzzah!
