Stay with in-laws, or hotel?

I am sure they would be offended

Irrelevant. You are of age when you don't have to please mommy and daddy, you shouldn't live to please mommy and daddy.
How you do it is important. You move only when you have all the details ironed out. Don't discuss, ask for advice, go back-and-forth
This trip is a toss-up whether it's more trouble to you to stay or go to a hotel.

However, you know what to do in the future.
