You guys have to visit after 4pm in the afternoon to watch the sunset. Nobody can enjoy sunset in Jakarta unless you go to Skye. They have seats that you don't need to reserve actually, just show up and buy some drinks or snacks there.

If people complain about can't get any bookings there, then it is normal in Jakarta for a new hang out place. Thousands of people want to be in Skye, you just need to be persistent.
