Welcome!
Before you begin to consider traveling, you'll need to have at LEAST 1-2 years of experience as an RN. Also, most travel contracts are for 13 weeks, working 36 hours/week. The shortest contract I've ever seen was for 4-8 weeks. You might be able to work per diem one weekend a month, but then you will be responsible for your own travel expenses & your own housing. I do not think you will be able to find a travel contract working somewhere only 1 weekend a month....
