I couldn't get any info on the shuttle as the folks in my office have been driving. One guy actually lives in that area and says he has seen the shuttles but has never used them nor can he vouch for the schedule/reliability. Maybe plan some extra time and wait for the shuttle, and if it doesn't show then just take a taxi, or a motorbike taxi if you are daring. Evidently the facility is beuatiful and the event has been going well. I think the semi-finals and finals are Sat. & Sun. Have fun.
