The Omni-Theatre is an unique experience as it provides really wide screen (not just left and right, but also above your head) to provide images to your peripheral visions. So, it does feel that you are almost there in the movie, similar concept to IMAX.
We watched the movie about the Dinosaurs, quite interesting and educational. However, would prefer the movie to last a little longer.
Best seating for Omni-Theatre: middle top part of the hall, in the section with lesser seat count.
Purchasing Omni-Theatre and KidStop as a package saves $2 pp. Go during off-peak period where are savings to the admission charges. Off-peak is weekdays outside school holidays.
