Is the VC Port a playable area or a skybox
Rockstar's own description calls it the cruise ship capital of the world, which is a lot of words to spend on scenery.
Ports in these games have historically been drivable industrial areas with containers and cranes. A cruise terminal is a different thing, with people and terminals and ships that are the size of buildings. If that is walkable it is one of the more distinctive spaces in the game. If it is a backdrop it is a wasted description.
