A privately owned, orbiting space station, built for the purpose of housing tourists in orbit, will be orbiting and will have housed at least one guest by 2025. Private individuals buying time on government space stations (such as the International Space Station) does not qualify as an instance of a "hotel" since it is built primarily for other research. If, however, the ISS is sold to private entities and converted to use for space tourists, that would suffice.
For the purposes of this claim a station is judged to be a "space hotel" if and only if the following four criteria are met:
1) The station is explicitly advertised and/or solicited as a hotel for space tourists
2) It has capacity and accommodations specifically designed for use by tourists
3) If it is used for other purposes (eg. an orbiting research platform for hire), a majority of its anticipated (by officers of the company) revenue will be due to tourists.
4) The station is not, itself, merely the transport vehicle but the destination. At least one tourist should arrive after the station is in orbit and at least one tourist should leave before it departs orbit.
The claim can be judged true as soon as all criteria are met. The due date is a time limit for reaching the objective, not a requirement that a hotel must endure until the due date to qualify.
