I've been loyal to Marriot and SPG for years, but the merger seems to have downgraded the benefits of both programs. I am currently Gold and about to be Plat in about 10 days. I had a reservation from 8Aug-30Sep about 54 days at this property. I spoke with the GM about a $35/day rate adjustment to meet my reimbursement amount. The response was a no. After the first three weeks, I had time to do some additional research and found out that if I booked my stay in 3-4 night increments, I would receive the rate that my company would cover. So I made about eight separate back-to-back reservations that would cover the stay. The day before checking out the original reservation, the Manager on Duty (MOD) told me that I would incur a one-night penalty for canceling the original reservation even though I would be staying until my original departure date. I asked for the policy to be shown in writing, and he stated that it's internal to Marriott only and would not produce it. I asked the front desk agent to put me in for a late check out because I would have to switch rooms, and she was granting it until the MOD came over and stopped it. When I stopped by the desk the next morning, the agent put me in for a late checkout so I could move my belongings to the new room as soon as it was ready. This was a perfectly reasonable solution. The challenge i have is that the MOD is attempting to implement a policy that he cannot produce in writing. Then it feels like retaliation with the denied late checkout because I told him that I would escalate this to Marriott Corp/Loyalty retention. I understand that each Marriott may have their own policies, but i have never encountered a one-night penalty because of an earlier-than-expected departure. When I contacted the Bonvoy loyalty department, they could not see a policy that included a one-night penalty at this property. Has anyone else encountered this or something similar?
