With that much computing power, they could easily grade each person's performance of their 'job' and that grade would then follow you throughout the park as your 'reputation'. This would allow everyone to have a good time (no one person can sabotage a mission) and your ineptitude would not reflect on my performance. In other words, the success of the mission is just the ride vehicle, how you got there is what really matters.
This sort of individual grading also means that you can have a completely different ride every time you rode it. Not only sitting in a different seat, but they should be able to track all of your performances for each individual seat. The best video game ever produced.
