I received an email today that effective November 1st, 2023, Mainport, Rotterdam "will no longer be associated with Marriott International but will continue normal operations and your reservation will be honored."
The rest of the details seem pretty standard for a property ending their relationship with Marriott:
- Prior to November 1st, 2023, if you wish to cancel your reservation or seek alternate Marriott accommodation; please call Marriott’s worldwide reservations
- For guests wishing to utilize Marriott Gift Certificates, Incentive Awards, or Gift Cards, this property will be unable to accept these as a method of payment beyond October 31st, 2023.
- Since the hotel will no longer be affiliated with Marriott, you will not earn Marriott Bonvoy points, nor will you receive membership amenities or benefits.
