 Connecting two vehicles and providing an airtight seal may be a complex process. The internal pressure on the seal will be significant, and the connector may require some kind of semi autonomous latching system.  Some form of electronic or mechanical interlock will be required to ensure that a vehicles does not leave until the inner hatch is closed.

 Although the hot exhaust from the engines loses its power rapidly, rocks and pebbles thrown up by the launch might be dangerous for a very long distance.  In particular, the low martian gravity lets ejected rocks move further than on Earth.
-Precision landing may be more difficult than expected, so a well defined spaceport, as illustrated, may not be possible. Rapid re-fuelling would be required to allow for a quick turn-around and maximum use of the spaceport during the relatively short synodic conjunction.

Alternatively, the ships can stay on Mars for an entire synod, white their return propellant is being produced.
