【正确答案】[参考范文]
Dear manager,
As one of the travelers who visited the park last week, I am not satisfied with some of its services.
Firstly, the price was much higher than usual, and we were told that it was the case at the height of the season. Secondly, ail the travelers were in disorder, for very few signs could be seen to show you where you were and where you should visit next. Besides, there was nobody in charge of the organization of travelers. Finally, rubbish could be seen every- where, but there were not enough cleaners to dispose the rubbish.
Therefore, I hope that some measures can be taken to improve the present situation. It would be nice if travelers could be informed of the price increase in advance, so that they could not feel cheated. What's more, more work could be done as far as organization and management is concerned.
Looking forward to your reply.
Sincerely yours,
