I have to chime in here as well to recommend the Bali Amans. The first time we were in Bali, we kept saying they were out of our budget....but the reviews were so fantastic.....we couldn't really get it out of our minds. In the end, we thought, well...let's splurge just a little bit and stay only three nights at Amankila. We spent the rest of our nights at the FS and a Hyatt to offset the cost. Many years and many Aman properties later we think this was the best decision we ever made.
If you have 10 nights, just give a few of them to Amankila. It won't cost you much more if you're willing to pay for 10 nights at the FS. Aman's have great packages with free activities for 3 nights and if you are on your honeymoon you can arrange an upgrade ahead of time. They'll be good to you.
By the way, I can't say I really like the FS Jimbaran. View is everything to me and I can't get over the airport across the way. The FS Sayan is in a much prettier setting IMHO.
