Hand on heart, how many Marriott brands can you name off the top of your head? 5? 10? That should be the range for most of us.

However, Marriott has the problem, like many other hotel chains, of having many more brands in their portfolio. 35 in the case of Marriott, to be precise.

To bring those closer to their Marriott Bonvoy members, you will receive 2,500 bonus points and a bonus status night per stay at any hotel brand for stays between February 26 and May 10. You need to register for this promotion by April 26.

This may not be the most generous promotion the world has ever seen, but it might be an incentive to brush up on your general knowledge a bit.
