Marriott has updated the program terms and conditions for Gold and Platinum member complimentary breakfast in Europe.
Gold and Platinum members can now choose between a breakfast for 2 OR 750 points daily at JW Marriott, Autograph Collection, Renaissance and Marriott Hotels in Europe if the lounge is not open.
You can access the Marriott Rewards Terms and Conditions here.
Here is the relevant part of terms and conditions:
Marriott Rewards has now aligned the breakfast rule for Europe with the one that has already been applied for a while in the US. You can choose between the bonus points OR breakfast IF the lounge is closed. Unlike the US, the European breakfast is not designed purely as a continental one.
