If I want to travel with my husband, do I need to let my in-laws know?

1, actually, you'd better talk to your in-laws. Out of reason

2. It's not an application to tell your in-laws, but to tell your in-laws that you are going to travel and relax yourself. You should carry it out according to your plan. If you think you can't talk, you can let your husband do it.

Don't worry about the opposition of the other party. It's two different things if you say you don't go out to play, and then your in-laws will complain more about you.

As the older generation, tell them that there are still some things at home that can be taken care of.

If they really keep opposing, then know the reason first, and then talk about it if it is acceptable, or arrange another time. If you don't accept it, make it clear to the other party.
