My friend wants to travel with me, but I don’t really want to take him there.

Then just say that you are going with your classmates. The main purpose is to get together with your classmates, play together, take a photo, etc. It is really inconvenient to take him with you. I hope he can understand you next time. Take him with you when you go out to play. This is just a talk. I'll talk about it next time. If you don't want to take him with you, just don't take the initiative to find him. In fact, it's nothing, and it won't hurt your feelings.
