Just received an email offer from MGM for some really good rates. HOWEVER, I also notice there is a "no cancellation" policy connected to this rate I quote from the site linked to from the message:
"This offer is non-refundable and may not be canceled or date changed. Rates may not be lowered once confirmed. Not available for existing reservations. Rates are subject to change and restricted dates apply."
So . . . be cautious when making reservations.
Could it be that the days of being able to change reservations/adjust rates on Vegas hotel rooms are coming to an end? Or perhaps this is an isolated case . . . but I've not seen it before.
