Could be worth doing a little homework on .. sorry to tell you now, but gee, some of the Hotel deals for Bali outta here when specials are on, are 10% of rack rate all things considered!
There are many travel agents here that basically sell nothing else than Bali. You can BUY a Business Class upgrade on both AN and QF and Garuda most times for $100 or so, as NO business guys use the route, and the planes clearly have C or F seats in place.
You'll love the food - and practice up on your Ozzie accent if you want to order anything!
