If you are going without kids or do not mind if your kids miss a couple of days when school starts, then I suggest your first day start on Jan. 2nd. We have gone 2 times during this week and after new years the crowd starts thinning and by the 5th the crowd is gone and it is a pleasant stroll around the parks. I would stay away from MLK weekend. My daughters youth group is going then and I know there is a big youth conference there. The last week in Jan. is good to. Stay away from Presidents weekend also, there is a big car race at that time. The prices on hotels drop the first week in Jan. to.
