The only thing I can add is that is probably better to take money/TC in your own currency as it will be easier to work out prices when they are quoted in RUP's. eg If you are an aussie and take American $ then you need to make two calculations ie from US$ to AUS$ to IndoRUP. Much easier to only do one calculation.

I have bought adapters at Matahari Dept Store in Kuta Square, in the hardware area and found them cheaper in Bali that at home in Aust.

Also a mixture of cash TC and credit card is the way to go. But watch out if you withdraw cash from ATM's is that bank back home will probably hit you with a fairly heavy transaction fee and also the ATM's in Bali give you your cash before they return your card, which is the opposite to that in Australia and you may get caught walking away with your cash and leaving your card behind - it is an easy thing to do.

Sorry can't help with the Contiki thing as I am abit old for that too.

Ohh and the mosquito's, we normally stay in a villa that is "open" to the air and we just go to the supermarket and buy mozzie coils and we find they work just right.

And by the way we will be there in August staying in Legian may catch up with you?
