Just to clarify...
According to the
T&Cs, to get room credit there must be a qualifying stay, which is defined as a stay for which the member is registered and pays for the room.
A Member is eligible to receive Points/Miles for a qualifying stay at participating Marriott brand hotels or Ritz-Carlton hotels for his/her room and up to two additional rooms.
and
A “stay" or "qualifying stay" means all consecutive nights a Rewards Program Member registers and personally pays and stays at any Rewards Program participating hotel, for which the room is billed to the Member.
The
rule for receiving elite benefits does not require there be a qualifying stay, just that the member be staying in the room. Marriott could have included the qualifying stay language in the rule for elite benefits but obviously chose something different.
Benefits of Elite Membership are reserved for Members only and apply only to the one guest room in which the Elite Member is staying. As proof of eligibility, a Rewards Program Membership Number is required when making reservations.
