Good point A_Heretic, the front docking tube is meant to be a maintenance/auxiliary docking tube for the crew, I intend to model a bigger, wider version for the side of the hull that has a less industrial look for welcoming the passengers.
A VIP yaghts dock is a splendid idea! I could model an extendable docking arm, but where to put it, the best spot would be on the rear end of the front section, perhaps near the top so that any docked VIP have a nice view on the arboretum
