Agreed, but a lot of resturants and other businesses give there help vacation at this time of year due to a slow business. that does include casinos as well I do not think there is a set time, but know that this is they seek the time off. After coming to the Island since the mid 80s. we have seen this happen when we would travel in the summer and fall. We have not done this of late, as we only travel in winter, but do not believe there is a real time table, but could be wrong....
