We are making a return trip in 2007 as well. This past Jan. we took my 3 year old step son. In 2005 and 2004, it was just my husband and I. 2005 we went in April and 2004 we went in February. I have to say, I enjoy all three trips weather wise. On our Jan trip one day was real cold and windy, the other days were in the upper 70's low 80's. We avoid May - Sept at all costs but other poeple enjoy going during those times. We just dont like dealing with the heat and crowds.
