what is travel nursing really like?

can someone who has been a travel nurse working in the united states tell me what the job is really like? all the benefits and pay seem pretty good and only working 3 days a week sweetens the deal but is travel nursing as good as the websites online make it seem? since you are constantly on the move, how do you deal with family and friends? can u really make a career out of travel nursing? cause it seems like travel nursing is only a temporary job. u can't do it all your life.

oh i'm new to the forum btw
