I emailed Kumala Pantai a few days back re. availability in early Sept - Received a response today -
We have 1 Ambasador suite ( 2 bedroom ) from 1 Sept to 5 Sept and the rate is Rp. 1.490.000,-/nettbf/night.
But we have 1 President suite from 1 Sept to 9 sept and the rate is Rp. 2.120.000,-/nett/bf/night.
I have booked elsewhere - but have posted in case anyone is interested.
