I suspect there are other contributing factors that will help. I'm not sure what, but Universals does generally have a good track record when it comes to high throughput rides. There might be some exceptions. Not sure what Rip Ride Rocket does. But most of the time Universal's rides do get very high through puts. In terms of Intamin, I know that some of their older rides are very slow to load (I'm looking at you Colossus), but looking on the Intamin website they are aware of this and their more recent train designs do tend to be a lot quicker to load. Admittedly when Volcano Bay opened it seemed to really struggle to cope with the demand (to put it mildly), but then again water park rides have always tended to have much lower through puts than major dry rides. Some of Universals recent additions have disappointed a lot of fans, but I still have faith that Universals will do something really special with this.
