At that time, I tried booking on the orange application using a referral code, it turned out to be cheaper, but because I didn't have a CC/debit card, I couldn't pay when I bought it in Singapore. Luckily, there's Traveloka that allows payment using OVO. Buying on an online platform is cheaper than buying OTS because the rupiah rate dropped a bit when I went there. USS is fun, it's also very suitable for bringing children. It's just that the queue for certain rides is quite long, even though I went there on a weekday and not during peak season. But, overall it's still okay, compare to my friend's experience who had a super long queue when I went there. Thank you
