My family is considering a trip around MLK weekend and for those who have gone during that time I could use some help. I know the crowd will increase, but wonder when that usually happens. Do the crowds start increasing the week before the weekend, the week after, is it just during those 3 days of the long weekend that the crowd is higher??? We are trying to decide if we want to come the weekend before (arriving on the Saturday evening of a marathon) and head home on the Saturday of MLK weekend or arrive the Saturday evening (wouldn't visit a park until Sunday) of MLK weekend and stay through the next Saturday. When do the Brazilian tour groups start arriving? We have been the first week of January several times and I realize there really isn't a slow time anymore, but trying to determine which scenario is best for our family. I would love to hear your thoughts and experiences!!!!
