Thailand is loosing it's traditional charm. Attractions are "manufactured". Development means McDonald's, Starbucks, more 7-Elevens. Unlimited visitors to islands and national parks. Lack of planning and the wrong idea about what proper tourists would come for.
One thing I always wondered for example is why beach front roads in Thailand always have to be the busiest and most congested. Traffic free areas at the beach front with quality shops, restaurants etc and walking zones only would be so much more appealing. Lead the main traffic another way.
But we all know that Thailand does things its own way, without much thought for alternatives. Some major improvements could be made quite easily, but unfortunately things move slowly.
