We just got home from a wonderful time in the parks...10 days in all. And already I'm hoping to go back soon. Am thinking of heading back down, flying this time, for a week in March. Would be a good way to celebrate my birthday. 
Which week will most likely be the least crowded? How long do the parks stay open this time of year?
