Ah, nice!
Sojourn is designed to remove the difficulty of crypto payments from travel while providing a rewards system designed to work for the user. Sojourn coins will replace traditional hotel loyalty points, which allow them to be used for hotel bookings on our future site, or traded/sold, whichever the user prefers. We will operate a hotel booking site that will accept most forms of crypto, and will issue Sojourn coins with every booking.
