Yeh I think the best tourist days for thailand are probably over.
Things have fully recovered from tsunami but severe political related issues & southern muslim terrorism are real problems.
We are under military rule currently & constitution is going through stages of transition to support military footing within politics, going be bit of a baby china and our dear prime minister has been sucking on chinas teat like a pattaya hooker :-/
free speech is suppressed, news heavily influenced or reporters arrested or sent for attitude adjustment.
The muslim issue only going get worse as it a growing global war world wide really & only one way to solve it which means digging up hitler or pol pot lol .
economy here plummeting so lot more crime which means tourist get scammed & robbed more.
The hannah & david deaths being a prime example of real thai nature, burmese where not in that alone or possibly at all ! shocking and shameful mess .
Any fight here with thais involve batons, knives, bottles, guns and they don't think twice about using them.
The erawan bomb was only about 3km from my home and my wife heard it :-/ walked past it weekly to go to our Big C supermarket too :-/
Gets worrying at times using public underground and sky train as I know how lapse security is lol .
Still can have a good holiday here but lot more care needed and more money as prices higher & foreign currency lower at present .
