The Marriott reports that it has sold all the rooms it can block for us for Friday and Saturday, February 16 and 17, 2018. (As of September 7, it was still possible to extend an existing reservation to Thursday the 15th or Sunday the 18th.)
Some rooms will open up as cancellations come in, as they always do - often in the last two weeks before the con. So keep trying... but make alternative arrangements in case the effort doesn't pan out. Check our Alternative Hotel page for overflow housing deals we have made with other hotels.
If you have a room at the Marriott, consider listing it on the Room-share page. You've no obligation to accept any particular offer for it, but if you wind up corresponding with someone congenial, you could make a new friend for life....
It's time to apply to be a volunteer at DunDraCon 42.
It's time to start getting ready to have a great time!
