@laborrn,
How old are the kids?
Where are you traveling from (as in, to California, but are you in Las Vegas or Boston)?
Also are you asking about just the trip from where you are now to California, or asking about traveling in general after you've moved?
Or are you asking about being a travel nurse, with husband, three small kids and a dog in tow?
Sorry for all the questions, just need to clarify what you're asking before I can give any useful advice!
