Which is better, the hotel or the tour guide?

In fact, tour guides are tired, but they can travel everywhere and have a lot of knowledge, especially when traveling abroad. Of course, the language is too good. First of all, English is better. Then Japanese and Korean are more popular. Hotels are not recommended because there is not much room for development. The salary is limited. Although the hotel is ok, the manager is not so good. You must be very capable of managing others in this position. I wonder how long it will take.
