universal studio was big (it was divided into upper and lower lot), however there was not many rides. several rides were under renovation, and the mummy rides unexpectedly closed down while i was on the line due to technical difficulties.
even if the ticket was 1 day get one day free, i think one day is sufficient enough to walk around and ride several rides in universal studio.
the tickets i booked from traveloka did not have a QR code in it so i had to go to customer service to get the physical ticket printed with the barcode. no biggies tho but keep in mind when you are about to book your tickets in traveloka.
