The cheapest Disney vacation needs to be timed right. Disney typically lowers resort prices in the off, or value, season--the fall and parts of winter. You also can save money by driving instead of flying and by not buying snacks in the theme parks.
Time your vacation for when Disney is offering reduced-price vacation packages. Find sales at Disney's website, disney.go.com. You also can watch for newspaper, magazine and television ads promoting special offers.
Staying in a Disney-owned resort will save you money. Resorts come with extra perks as well, such as free transportation to the parks and early park admission on select days. Choose a "value" resort, such as All-Star Sports, for the most savings.
Buy bottled water and snacks to take into the theme parks. As of 2010, a bottle of water or soda in the parks cost $2.50, so food and beverage costs can add up quickly. Pack your own breakfast items, such as bagels or doughnuts, to lower your costs further.
