Did you ever wish there was someone out there who you could contact with an issue or problem? I have and it seems that I've had fair to middling luck with complaints and suggestions about travel with airlines and at times, even hotels (not necessarily Marriott but a few times) The use of computer generated responses to emails makes it much easier for the other party ot merely insert the appropriate paragraph ("we value your loyalty" is one).
National Gerographic Traveler magazine has a person who specializing in taking issues and answering them. Here is his blog.
He seems to have his finger in a lot of pies.
Is there a need for this kind of thing for Marriott Rewards? Just wondering.
