Technically, the busses are for WDW resort guests only. However, on our previous off property visits, it has never been a problem to get on a bus and go to a different park, and then come back at the end of the day and get out car. Is there any indication that this is changing with the introduction of the wrist bands? Previously, short of asking every guest as they board the bus, there was no way to know who was a resort guest and who wasn't. Now, however, the bus driver will be able to see who has a wrist band and who doesn't. So I am curious if they are actually enforcing the rule now that you must be a guest of the WDW resort in order to use the bus, now that they can see a wristband, or lack thereof, on people who are boarding. Our next visit may very well be offsite and I wonder if we will have any problem taking the bus if we desire to?
