I just got the following email
Dear Guest,
Sonder’s licensing agreement with Marriott International, Inc is no longer in effect. As a result, Sonder is no longer able to honor your reservation.
Further information can be found in this press release issued by Marriott which contains the following:
“Marriott’s immediate priority is supporting guests currently staying at Sonder properties and those with upcoming reservations. Marriott will be contacting guests who booked directly through Marriott channels, including Marriott.com, the Marriott Bonvoy App and Marriott’s worldwide reservation centers, to address their reservation and booking needs. Guests who booked through a third-party online travel agency should contact those organizations. Marriott remains committed to minimizing disruption to guests’ travel plans.
Guests with questions about current or future reservations at a Sonder property booked through Marriott channels can contact Marriott customer service here”
We apologize for any inconvenience this may cause
(links in the mail removed)
At least our corporate rate does not mean pre payment, so I have no outstanding amounts to get back from the credit card company.
