How the low / senior prices of Marriott Bonvoy works
With the introduction of the low / high-season rate, you can use this certificate in category 1 to 4 hotels all seasons combined.
On the other hand, for category 5 hotels, it will be possible to use the certificate for the low season (30,000 points) or standard (35,000 points) rate.
But it will not be possible to use it if the category 5 hotel is in high-season prices (40,000 points).
