Hi Peter, and welcome to planDisney!
It does not matter how you get to
Walt Disney World Resort, as long as you get there. The same goes for the airport you choose to fly into; it will get you to your destination, which matters.
Though the transportation offerings are different than the ones available at Orlando International Airport, you still have some choices when it comes to arriving via the Sanford Orlando Airport. The good news is that you can have your choice of shuttle services; just a matter of finding one that fits your specific needs. Another option would be to rent a car because it allows you to get where you need to go without waiting. If you rent a car, you will have to pay to park at the resorts, but not at the theme parks if you are a Disney Resort guest. In addition, you can opt to use one of the smartphone rideshare companies. If you choose to use the shuttle or one of the rideshare mobile apps, you will have access to the
Disney Bus,
Disney Monorail or
Disney Skyliner while you are on property.
Please let us know if you require additional assistance.
Have a magical time!
