Have you enjoyed yourselves
It is my great honor to provide services to you on this trip ,and it is also grateful to support me with buying my photos .
And I will scrape this money up for my college expenses .Welcome to visit Korea next time .Good luck .

有没有错的要走纠正地方?

个人觉得语法没啥问题
意思:你们此次玩得还算愉快么?
我很荣幸为你们提供此次旅行的帮助,对于你们买我的照片所给予我的支持我很感激.
我将把这些钱用在学费上.希望你们下次再来韩国玩.祝你们好运.(饿~我不大明白为啥要用good luck - - 还是别用了吧)
