How much would it cost for 3 days at disney world & air fair?

From LAX to florida and 3 days at Disney World to visit all the parks (not including hotel, food, %26amp; souvenirs) thanks!How much would it cost for 3 days at disney world %26amp; air fair?
A one day base ticket for a Non Floridian adult is $85. If you wanted to add park hopper, waterpark %26amp; more or no experation date to the ticket, it would cost more. You're looking at, for one adult with just a base ticket, $285. Then you have to decide which airline you would like to take and the hotel you want to stay at. Disney World has their own hotels on property, but at a cost. The onsite hotels can be worth it depending on your needs. When you stay on property, you get buses %26amp; sometimes boats that take you to and from the hotels and parks. You also get to go to a park earlier or stay later, depending on that days extra magic hours. When you stay at a DIsney hotel, you can take a Disney bus from the airport to where you're staying. They have Value, Moderate, Deluxe and Villas. The prices vary and are changed depending on the time of year.
