Hello, We are so excited and in the very beginning stages of planning a trip to Disneyworld in January 2015. We can't decide whether to go the week of January 10 or January 17. The 10th has several days that include Disney Marathon and the 17th includes a busy 3 days for MLK Jr. Birthday. Has anyone ever gone during marathon weekend and how did it affect the crowd levels? Decisions, decisions Thanks!
