After much discussion my extended family has come to the conculsion that the week preceeding Memorial Day in May is going to be the week for our trip. My family is used to going in early Dec. so I am concerned about the crowd levels. The touring guide page lists at a 7, but Mousesavers says it is a preferred time which seems to conflict. SO.. how bad will it be and how can I make the best of our time? Is it worth it to purchase the touring guide? What exactly is it? THANKS!
