Hi Kyle, and welcome to planDisney!
You have asked a great question, and while
Walt Disney World Resort does not offer discounts on flights or baggage services, you can always find a few specials and discounts that individual airlines offer from time to time. I know that if I search often, I can find offerings that fit into my budget.
If you are arriving via the Orlando International Airport, you have transportation options. You can utilize bus services such as the Sunshine Flyer or Mears. You can also hire a car to transport you to the resorts using a smartphone ride-sharing mobile app and have them pick you up. Lastly, you can also rent a vehicle from one of the various rental car agencies at the airport.
We are here if you have additional questions prior to your arrival.
Have a magical day!
Raquel
