The only real suggestion I can think of, and honestly I think it would be labor intensive and not fit the whole there's a 100 passenger thing is possible making the positions of where they stand/are fixed (Like sitting in all the chairs at dining hall, in various spots in the pool, hanging around arcade machines) In this manner the player would be able to run across names much faster and fix clipping, and it could even open up some avenues like clothing revealing something. (Ex: passengers wearing underwear/skirt/tight could be seen "better")
Once again, I don't think this update would be worth how many hours working on it. But an idea.
