Seriously, lots of time/little money is why Thailand was invented in the first place. Rock up on Tonsai beach today, just as the high season is winding down and you'll have no problem negotiating a bungalow for less than $300/month if you tell them you plan to stay a while.
They have good enough internet for casual remote work, good power, awesome rock climbing, Australian girls sipping stiff drinks out of a coconut, and all that James Bond Villain Headquarters scenery that Thailand is famous for.
And there are roughly thirty thousand equally nice beaches scattered across this world that will offer pretty much the same combination of cheap living, paradise, and wifi.
Sucks to be the rest of us. Keep us posted!
