Tax The Tourists To Stop Overtourism
Things like limiting the amount of tourists that can show up or extra regulations do not work very well and should be rarely used.
The two best ways is to increase tourist taxes and fees like some countries are doing. These should be carried out through measures that directly effect tourists and focus on them. Think about increasing hotel occupancy taxes and fees to get into certain tourist attractions. Tax the sale of things like gifts to them and various forms of refreshments and entertainment.
The other move that the Netherlands is doing is stopping the promotion of tourism for overtoured areas. That's perfect! Just don't spend money on advertising to create an even bigger problem for yourself.
Only after these two methods have been explored should more serious methods be considered.
If only every problem could be solved so easily lol.
