Question for the folks who have purchased a Disney vacation package in the past---Normally my family and I pay for our tickets to the park and our hotel separately, we usually stay 2-3 days. But our next visit will be a 4 night, 5 day trip. In your opinion, is it more economical to purchase a package..or piece it together yourself? (We typically stay across the street at the Carousel..Del Sol..Desert Inn..)
