Yes, you can bring luggage on the Disney resort buses, but there are specific practical considerations you should keep in mind. While Disney’s internal transportation system—which connects resort hotels to theme parks, water parks, and Disney Springs—is primarily designed for day guests, it is common for guests to transport luggage between resorts or to the theme parks if they are utilizing "luggage storage" services. However, the buses do not have dedicated luggage compartments or under-carriage storage; any bags you bring must be carried onto the bus and kept within your personal space. This can be extremely challenging during "rope drop" or park closing times when buses are standing-room only. For a more seamless experience, if you are moving between Disney hotels, you can utilize the Disney Bell Services, which will transfer your luggage from one resort to another for free (though a small tip is customary), allowing you to travel to the parks unencumbered.
