Yeah, as you say, it's definitely happening and it boils down to how the influx is managed.It can't be just unfettered slather.
Many small businesses make welcome money off the tourist trade and i'm one of them - and i love them. They come, they're in a good mood, they have a good time, they spend their money at local businesses, the bars liven up, and then they go away again. I think it's a great industry. If properly managed.
But that's your independent tourist.
The tour bus hordes, on the other hand, spend all their money at specific hotels and the tour companies. In fact there may be a net drain on the local economy given the money spent to maintain toilet facilities and garbage collection and repairing the stuff they've trampled on.
Meanwhile, we had the Hualien mist going today, though the clouds were not wreathing quite as poetically on the mountains as nuit depicted them.
