・lodging trip
・training camp

「合宿」可以用英文 lodging trip 或 training camp 來表達。

I have a university seminar lodging trip next week, so I won't be able to participate. Invite me again.
（來週我有大學研討會的合宿旅行，所以我無法參加。下次再邀請我吧。）

When I was a university student, I got my license at a training camp.
（當我還是大學生時，我在一個合宿營裡取得了駕照。）
