I haven't seen anything yet for this year's Cyber Monday (November 28th), Marriott has run some in the past
As last year's players can tell you - this is not for the faint of heart. Be prepared to be aggravated, irritated, even hosed (see above), but if you've finished digesting your Thanksgiving Turkey (or any of the terrific dishes listed above courtesy of Insiders) then dive on in and see if the travel gods are smiling on your plans, you just might snag a deal.
Here's an upcoming offering of deals scheduled for November 6. Since the best deals go very fast, it's important to know when it begins - which we are asking for an Insiders heads up.
There's no hint that Marriott will be doing anything for Cyber Monday but generally Black Friday/Cyber Monday announcements are made only very shortly before the day itself.
As erc has added, any Cyber Monday offers may well be folded into their "Holiday Rewards" promo. That initially confused me, since to us in the EU, November is simply a cold month in the middle of Autumn of no special significance holiday-wise, but I keep on forgetting about your thanksgiving.
I enjoyed Marriotts last daily promo a couple of years ago, PerkBreaks or something like that. I bagged a half price point weekend so look forward to seeing what this turns up.
