Robocall claiming I had been "randomly selected for a special gift from Marriott Hotels", and to press 1 for more details and 2 to be placed on a Do Not Call list.  Hung up after a couple seconds when I did not press any key.
This is a cell phone number, so it is doubtful that Marriott would be making promotional calls through it.
This is more than likely a phishing scam trying to get credit card and other personal information.
