Is it true that to visit Bali visa-free, you only need a round-trip flight ticket and hotel reservation?

Traveling to Bali is visa-free, but usually you do need to provide round-trip air tickets and hotel reservations as proof of travel. But this is not the only condition, there may be other requirements that need to be met, such as holding a valid passport, travel insurance, etc. Specific requirements may change, and it is recommended to consult relevant official information before traveling.
