CGK

Last month for the Do, the North America attendee stayed 3 days only. Good for a mileage run for a long weekend (being Monday is Memorial Day)

Is Bali expensive? Well, it depends. But it's always Bali offers a range from cheap to very expensive.
The spa we went it was very reasonable rates, about CAD20. For the same stuff, in other place like the famous RC spa, it will cost CAD125. (perhaps my comparison is not really accurate, but just an approximation.)
I had lunch for three persons in a good Balinese food in Denpasar, the bill was about CAD15. But we had dinner at LaLucciola by the beach to see the sunset as well, we paid about CAD60 per person.
