The week totally before Thanksgiving- in other words you would be checking out no later than the Saturday before Thanksgiving- it is the most possible week of the fall once the Food and Wine starts but if you go at all into the week including Thanksgiving your chances of getting the room decreases significantly. Also if the food and wine ends later at all then your chances will also decrease. If you dates can fall completely after the food and wine and do not include any day of Thanksgiving week (including the Saturday before) then you have a good chance.
