I think it is a points booking and Xmas period. Yes, not terrible really even though I wouldn't call 200$ all in a bargain. If you are Diamond you could just stick with Jimbaran Deluxe room (likely upgrade to Singaraja room as Amb and / or Diamond) and have the breakfast as your choice amenity.

Then spend the 200$ a day on meals and drinks during the day. Depends if you would be keen on afternoon tea, a bunch of drinks every night etc. It adds up quickly in the end and don't forget the Club room upgrade as well. YMMV.
