This level's a bit of a dumb speedrun because (as far as I can tell) no matter how fast you go in the first 9 minutes, the Tycoon VIP will always come on October 17th, so the whole thing pretty much comes down to how fast you can get him in and out the park. With that in mind, I got a lot of runs around the 11-11:30 mark, but decided to stop here because sub-11 is clearly the best milestone possible on this map.
