....Great start ... very good :)
Nowadays, a growing number of travelers have chosen to pay a visit to foreign countries instead of native scenic spots.
.... well this disturbs your flow... the first sentence give a fabulous entrance and you are again going backward with this. I suggest you to remove this line.
Some people claim that foreign visitors should pay more money for their travel than the native, in order to reduce the negative influences from international travelers.

However, I totally disagree with this opinion and believe that the same prices should be charged for both native and international travelers.
...this is also good.
