Sonder, a short-term rental company, has announced plans to cease operations and file for Chapter 7 bankruptcy following the termination of its licensing agreement with Marriott. The abrupt decision has left guests scrambling to vacate hotel rooms, with some given less than 24 hours to leave. This partnership, which was deemed a hospitality experiment, ended in chaos for many customers as they faced disrupted vacations and uncertainty about their accommodations. As Sonder begins its liquidation process, the fallout from this breakup is expected to affect global tourism and challenge the viability of tech-first hotel models.
