No knowledge about Indonedia, but 50 cents about nets: use your clothes' line to hang the net when no place to screw or the ceiling is too high to tape. We have a Sea to Summit
. It looks way to expensive just for a rope, but it is so well conceived that it is worth every penny, really (and so tiny!). Always a great way to dry clothers -or to hang the net.
Because of this, we got two Sea to Summit single mosquito nets
. Take reasonably little space -ca. as a single cotton, not silk, travel liner- although I would like a tighter bag to make it more compact. The net is a little too small IMO, but ok, although if you are tall you can touch the net while sleeping. Black colour allows you to see much better through than white.
I think an option might be one double net and one single net, for the times you have two separated -fixed- beds. Look for prices, some terrible differences from one place to another
Have a safe and happy journey,
PS: Get silk linens against bed bugs as well, but be sure they don't fall short to cover the pillow.
