I worked, traveled in Indonesia for a few years eons ago. Mainly Sumatra, Java and Sulawesi. Spent good time in Raja Ampat. Bali is meh and has been since the bombing. It was full of drunken Aussies. The Balinese moved out now leasing to Muslims. The temples sadly are not worth visiting now imo. Ubud sucked even back 15 years ago as stated.
Rural Indonesia is very cool, but it's rough. Little AC, no ice, always hot and pretty much only local food
What do you want to know? When are you planning a trip? June July best
