My husband has traveled with coworkers in the past and put both of their rooms on his MR#, and paid with his credit card. He's had no trouble getting credit for 2 nights (1 night each for 2 rooms) or even 3 when there are 3 rooms. They show up separately on his account activity.

Recently we (the family) have started traveling with him and I just noticed that the one night we spent at a Marriott in two rooms was only credited as 1 night's stay. The total points for both rooms showed up as a single line item on his account activity. I *think* that the difference is that his assistant reserved 2 rooms under 1 reservation instead of the previous method of 2 separate reservations.

I don't see this addressed in the T&C. The fact that a member can earn points for up to 3 rooms is addressed, but not the night credit. It would be nice to have the extra night credit - should we just make sure there are two separate reservations?
