I very much doubt that any Thai party at this time has a 'long-term tourist strategy'... (After all, Thailand, officially, doesn't have any immigrants, just migrant workers, supposed to 'go home' after X months, and us tourists...)
We'll just have to suck it up and wait what comes our way in regards to how often and long, and under what conditions we will be welcome or not...
Anyhow, Thaksin (inofficial leader of Pheu Thai) wasn't very foreigner-friendly, and neither is Anutin, so I neither expect anything 'good' for us from Anutin's party, nor from Pheu Thai.
