I have posted my reply on the economic issues in a new thread. With data.
As for Pattaya specifics, well it just needs to learn to adapt to the exchange rates. Find new customers, look for efficiencies & compete hard to keep the customers they do have.
The hotels are still great value compared with Europe. The hookers are great value compared with most places in the world.
Food can vary from good taste and fantastic value to poor taste and higher than UK prices.
A Starbucks coffee costs more in Pattaya than London, but we still have some good independent coffee shops.
