What's a good and bad tourist? You build a city like pattaya on the back of booze and prostitution then moan when the tourists that arrive are seeking just that, every other shop is a bar, weed shop or indian restaurant. If you want "quality tourists" then clean up the city to make it less appealing, but remember people in glass houses shouldn't throw stones, clean up the brown mafia, clean the beaches, stop long term scams like the jet skis, stop building until you have adequate drainage to prevent flooding
