I agree that depending on the time of year it may be better to stay on site but in the prime season of summer discounts are hard to come by. For our family it worked out better to rent a car and have the freedom to get groceries to make some meals to save money. Plus having the Disney Visa has allowed us to accumulate enough Disney Dollars that parking is always free. I have always been a strong advocate of staying on site and it really took a lot to stay off site but after having the freedom of having your own car and a much bigger living space I am more than happy to do it again. Every family is different and what works for one may not work for another. This happens to work for us.There are so many benefits to staying on site, and depending on the time of year it can be more cost effective to stay on site. With benefits like Magical Express and the Disney transportation system, I dont know how anyone stays off site.
