Multiple City? or Roundtrip Flight Itinerary?

I am planning a post college graduation (budget) trip to China/Vietnam/Cambodia/Laos with three friends and we are searching for airfares. We do NOT, ideally, want to have to return to a hub like Bejing for a return flight after 6 weeks of traveling South.

Is buying a multiple destination flight just as good a deal?

Also, if we are planning on taking other flights (domestic within China, international from China to Cambodia, etc), should we try to include those on the multiple city flight itinerary, or purchase them separately?

I'm still a little new to traveling, so any advice would be EXTREMELY helpful! Thanks! Reply to this
