The DHS and AK busses used to terminate at the TTC, where you had to transfer to Monorail of Ferry to travel to the MK. The TTC was als the hub for the Shades of Green bus that only ran between SoG and the TTC, where guests had to transfer to monorail (MK, Epcot), Ferry (MK) or bus (AK and DHS). Obviously this is no longer the case.
