The family went out to travel and formed a group.

Dude, stop it. The name of the tour group is the name given to you by the travel agency according to its own regulations when arranging your itinerary and booking a hotel. What's the use of having a name? At most, it is "how many VIPs are there in XXX's party", which can be used when picking up the plane or the train. I've been traveling in Guilin for so many years, and I've never heard a guest give me a group name. You are very talented! I hope your group name is useful! !
