You are ready to travel !!
You have alot of experience and ED nursing has the most travel opportunities.. You will be fine.
Just make sure you don't have to always cover the psych. ER ward, etc. ask for equity during your interview.
It seems like most of the travel problems are floor nurses who have to float and do split shifts. ER nurses don't float, unless, they are in a small rural hospital, then they go go to ICU.
Have you talked w recruiters yet? Go for it......
