My theory for boarding the falcon, assuming walking onto a falcon is not part of the game plan:
You enter a crate in the preshow, effectively smuggled/trafficked onto the falcon, so that you and your flight crew can steal the ship to complete the mission. You enter a small room and are made to believe that youre in a shipping container being lifted by a crane of some sort into the falcon. This will be like the false elevator in journey to the center of the earth while also limiting the number of guests entering the falcon at a time. You then emerge in a cargo bay of sorts within the falcon’s rich interior. Never needed to walk into the ship. This tonally would match with the name/plot of being a smuggler and completing missions using the falcon, though it does lend itself to be a little more dark in that you are stealing it to steal some more rather than flying it in an epic battle of good versus evil.
