The VR Headrock website has clear direction on getting to VR headrock. The ticket purchase at counter is quite seamless if u used SG rediscover voucher. Each game on average is less than 15 min, so I would recommend buying 5 or 6 games. My personal recommendation are:
1. Jungle rafting
2. Extreme train
3. Storm Blizzard
4. Zombie busters
5. Jump jump (but VR set stinks at this station)
I didn’t enjoy flying dive as image is blur and crotch area might be a bit uncomfortable from hanging mid air.
