Yep, I got the link this morning and finalized it. I have no expectations that it will be worthwhile, but it doesn't hurt to sign up and check it out for myself.

I think you're also a UA person, as am I. This feels different to me than when UA made the big survey push a few years ago. Customers were very unhappy and leaving quickly for AA and DL. I think that was more about making customers feel they were being heard to save the sinking ship. Marriott doesn't seem to be in that same position, so the fact they're spending some money to do the surveys gives me a little hope that they're really looking for some customer input.
