Does WDW transportation still run as normal after Magic Kingdom E-Ride Nights?
Yes it does, even though the bus drivers don't announce it during the day. The buses come much farther apart, but there still are direct buses to the resorts from the MK. For example one guest reported waiting 20 minutes for a Port Orleans bus, in that time 4 All-Star buses showed up.
The boat transportation MAY not operate after E-Ride Nights. So those who took the boat to the MK (from Ft. Wilderness, etc.) must use the monorail and busses to get back. Check with your hotel to be sure.
