We had a budget of $2,650 CAD for the month of May, and we spent $2,455 CAD ($1,808 USD, €1,700).
Pretty happy with that, considering we started the month in Spain, we brought Max on a 28 hour boat ride, we toured the entire south coast of Ireland, then drove all the way across the country and spent a couple of days touring Dublin. I'd say we did really well!
