I am sure that MR considers a whole bunch of people calling to switch their Mega bonus promo, but Marriott, like most travel companies, would be well served to treat all of it's very loyal customers nicely, and not favor Plat members over Gold. Good and loyal customers are hard to come by for any company.
If someone is calling up and saying, hey MR, I am planning to be staying 20 or 25 nights in Marriott brands within a short period after February 1, and I do not like the stay 2 nights, get one 1-4 cert offer I received, please switch me to whatever "buncha points" Mega bonus promo, because SPG, or Hyatt, or Hilton, or the man in the moon is offering a better promo if MR is unwilling to switch me, but I would prefer to stay with Marriott. Also, my friend "Plat123" switched, so I want to be switched too. If MR answer to that is, "Sir, we only switch Plats for this promo period, and you are only Gold789," then if I was Gold789, I would be looking for the best deal out there for myself too. A company saying we are only doing nice things for 75 per year guests, and not for 55 per year guests, that is bad PR, very bad.
I am sure there will be a bunch of people who do not agree with me on this, oh well.
