Is DS, Disney's Hollywood Studios (DHS) or somewhere else?
If you're asking about DHS, then it's "faster" to take the bus. You can walk from MK over to the Contemporary and then catch a bus directly to DHS. Alternatively you can take the ferry (or monorail) from MK to the TTC, then catch a bus to DHS.
If you take the monorail you'll need to take the monorail (or ferry) from MK to TTC, then take the monorail from TTC to Epcot, then transfer to the bus from Epcot to DHS. There is no direct monorail from MK to DHS.
