Amanjiwo - hmmmmm. That's Java, right? Stunning property! My husband and I are going to Amankila in the fall (also Indonesia) but Bali is a mostly Hindu island rather than Muslim. I guess I would be hesitant, but I'd be more inclined to go to Java than to say, Amanpulo in the Phillipines. The idea of being kidnapped from a remote island is too much for me!
Whatever your decision, I hope you have a wonderful time! It's nice to hear from a fellow Aman junkie.
