Can you take DME to different resort?

Disney Magical Express is for any resort guest. If you’re not checking into your hotel right away, can you take the DME from the airport to a different resort to begin your stay. For example, if you wanted to eat there?

Officially no.

However if your bus was doing a loop of other resorts , there would be nothing to stop you getting off early (or late).

They do scan bands or check paperwork again before actual boarding, so you can’t just choose a bus to board.
