When to take a permanent position as a traveler?

Hi all you all nurses!

I completed my degree in an accelerated program - bsn->msn and am fortunate to have reputable jobs already under my belt.

What I really want to do is explore palliative and end of life nursing as an adult NP. I have three months to schedule my boards. I am working as a traveler with the intention of studying for the boards, and have been offered a permanent position - they want an answer from me yesterday. They understand my goals and are saying all the right things - how do I decide?

On the one hand, I feel like it is a great opportunity, and others are struggling to find work, so I should jump on it.
On the other hand, it is not the ideal location - and I just started traveling!

Any thoughts?
