Do you need park entrance to ride the monorail? Can we get on the monorail in DTD and ride it roundtrip if we do not plan on entering the parks that day?
We've always been able to ride the whole loop from Disneyland and back. We've never been required to disembark at DTD, but they do sometimes make everyone disembark at the DL station. In regards to the OP's question, they scan park tickets and check bags at the entrance to the DTD station since the next stop takes guests inside of DL.
