Vigan-Laoag Trip

We are planning to stay in Vigan sometime this month for 2 days.. Our plan is to go to Laoag after our two-day stay in Vigan. Does anyone think we should do Laoag first then Vigan? Or are our plans just right? Also, should we stick to our original plan of Vigan-Laoag, what mode of transpo should we use? Bus? We don't know anyone or anything in Vigan, so please help! Thanks in advance!
