Yes, if you are staying at a Disney resort, you can reserve the Disney Magical Express bus for transportation from MCO to your hotel. The service will also handle your bags for you so you don't need to pick them up at the airport. There is a sticky thread on this board with details about DME.
DME is free. This works out for you because you don't need to pay to get to your resort hotel. This works out for Disney because you won't have your own car to leave and spend money offsite.
Note that not all Disney property hotels offer DME, for example, the Dolphin and Swan are not operated by Disney and so DME is not offered. Disney-official resorts are available for DME transport.
