Sonder properties are no longer Marriott-affiliated.

Hotel guests across the world have been kicked out of their rooms mid-stay after Marriott's partner Sonder suddenly declared bankruptcy. The abrupt shutdown has left travelers stranded from Boston to Dubai, with some returning to find their luggage stuffed into plastic bags or dumped in hallways.

Sonder, once valued at over $1billion and hailed as a rival to Airbnb, filed for Chapter 7 liquidation on Monday after Marriott International terminated its licensing deal — forcing the company to wind down operations immediately.
