I went to this spa 'resort' in Batam with a gf. Had a quickie there but nothing else since that day was purely for relaxing.
Welcome to Batam Spa Villa - Packages
OK, nice spa villas but the 'resort' swimming pool is very dirty there, so nothing to do but wait for your turn at the spa.
Overall, the masseur were quite good but does not leave much for privacy unless you dismiss them.
But the spa villa is nicely decorated with a jacuzzi facing the sea.
There are the holiday chalets but the place is quite spartan. The resort reminds me of 1980's Desaru - nothing much.
Taxi to town centre costs S$25 so bring along your own entertainment (or just stay in the chalet and fuck, fuck, fuck and fuck some more). Remember to bring lotsa snacks and lube.
Fuck away!
