Unless your a large corporate I don't think Marriott is capable of noticing this. They don't seem capable of realising that just because someone does 100 nigts with them that they are missing out on another 75 due to their poor service, all they see if the 100 nights they are getting. That or they have decided that to give better CS isn't worth it, which short term may work, long term of that 175 night total in a few years maybe near 25 nights with Marriott, specially for those with lifetime Titanium, afterall what does Ambassador get you these days, the answer being pretty much the same as Titanium!
