Or Thailand in general?
When I first started coming Pattaya was very much a 'Man's Town', where it would be rare to see families or groups of females apart from Thais. It was kinda the wild west, where most there knew what they were there for, Thai or farang. Beach Road was rammed with freelancers, there was no big shopping malls bar Royal Garden, Mikes, the Bid C's etc. Infrastructure was not as it was today, in general a lot more seedy.
Now the place is coming down with families, groups of middle aged females waddling across 2nd Road, big flashy malls, loads and loads of Chinese, Indians, Russinas etc, loads more choice in food outlets, places to go or see. Yes the 'girls' are still there, but no way as in your face, it's different, sanitised to an extent if you like.
On trips to Thailand, I spend a few days in Pattaya, I have a small condo there, but the changes now suit me as I visit with my wife and young daughter (who's 2). Things like all the very nice kids play places in Central, places like Central full stop, all the new choices we have, and of course the 'girls' aspect changing doesn't impact me now.
That said, if I was of the same mindset as when i first came to Pattaya 12/15 years ago, not married, I would not be happy with the changes. I'd have preferred it the way it was, more like the wild west, a man's town, wanting the 'sex and girls' more in your face etc.
