I like the Cove Eco response, but is the amount per night or per stay?Here is what a decent operation in Raja Ampat writes about tipping a week stay,
Extract below from their website FAQ page. That's Cove Eco resort, FYI 1,5M IDR =100USD
Why would an operation that charges you twofold need more tips?
The fact they give you the option to contribute to the tip box or give directly to the person is great and should be the standard like in most other countries. I spoke with a few good guides, they all hated the pooling system, and they said those rules are in place mainly because some office staff are jealous.
Not all guides or waiters or housekeeping are equal so I don't see why anyone doing a below average job should share the tip of the top performers.
