I have a friend who works for Marriott Corporate, and she's told me that they are not allowed to participate in the Bonvoy status program. I've always thought that was very short sighted on Marriott's part-- their employees have no particular incentive to stay at Marriott properties (other than the employee rate, when available) and have little to no idea about the loyalty program and its benefit (or lack thereof). I'm very glad to hear that Hilton lets employees participate, and that the terms of their participation are the same as for non-employees; I'd suspect that their employees who do travel probably have a better appreciation of what it takes to become a HHonors elite member, and of the value of the various benefits thereof than do employees at Marriott.
