Once again Mike, you hit the nail on the head.
In the late 80s up to the early part of this century, Phuket was approaching idyllic and my "go-to" destination, and I visited every year. That has changed in so may ways, such as you describe. Add to that the fact that nearly all the friends I made there have moved on or sadly died, I've no intention of visiting again.
However, IMO, you and the government / tourist association have missed one vital point: comparing Phuket and Pattaya is like comparing chalk and cheese and always has been. Pattaya is as you describe plus it's brash and edgy and you love it or hate it.
Personally I'll be arriving there in a little less than a month and can't wait! However 2 months there will be enough - time to go.
