Guy, the "Phuket Sandbox" is NOT OFFICAL yet. The government (and Bangkok post) have been talking about it since LAST July. Remember when the private plane flew in 2 people to Phuket?
We're not approving anymore daily questions asking about it and please stop making comments stating it's offical because some guy on Twitter "tweeted" about it (I swear I deleted a comment from a Thai woman who said it was official and cited David borrow).
Just be patient, no one would be happier for this to happen than me as I'm planning a July return to Thailand myself, but it's been planned and canceled numerous times already, just have to wait and see.
