How about traveling alone with a group?

No problem. Besides sleeping, you may have to share a room with others. But if you want to own a room, you only need to pay the room price difference for one more person. Easy-going personality, more communication with people; If you don't like socializing, then go, eat and play with everyone. It all depends on your personal interests. Anyway, it's only three to five days, and one person can join the group. Besides sightseeing, you can also study people. I think it's interesting. Just try it.
