For 3 million Euros you get 18 weeks of preparation on a Caribbean island, the flight into space and three nights in the orbital hotel. During the stay you get to participate in space experiments. (Its not clear whether you are the subject of the experiments.)
As far-fetched as this may sound, the company reportedly received $3 billion in backing from a space enthusiast to build the hotel. That backer must be one of the 40,000 people in the world who could afford to stay at the hotel.
