Yes, greed is my second name!
I am not sure what you mean by "seatbelt checker". I was referring to the second character (guard) who could ensure Rebecca is properly strapped into her seat. To do so, she would of course have to stand in front of her, bending over slightly, showing us her shiny butt. But no matter which direction she ends up facing, I am sure you will make her shine. Pun intended.
As for the directions of the seats. Yes, troop transports in most cases have this setup, so do public transports. But I don't think this rule applies to such a high-velocity means of transportation. Then again: fantasy, DUH. Ignore me trying to be a smartass
