However, college students, especially you, are willing to pretend to be fat in the face, and certainly don't want to say it in front of your classmates. The only way is to ask friends or classmates around you if there is a place to stay temporarily for a few days. After all, it's summer, so long as there is a place and it's convenient to sleep, you can also make a floor.
In addition, you should spend more time these days to find out which parts of the city have characteristics and spend less money. When we go to other places to play, we always want to visit some places with local characteristics and eat snacks, so that we can have fun and spend less money.
As for the rest, I think you are college students, and it is normal to travel in poverty. As the host, I think we should formally invite them to dinner, just go to a scenic spot where tickets are charged and walk around. You can't pay for all the scenic spots, and you can't have a formal dinner. Therefore, having a place to live costs several hundred dollars for a meal and several hundred dollars for a play. If you add up the pieces, it should cost thousands of dollars.
