What to do in Ilocos...

I'm going to Ilocos with Tita Susan (and maybe Tito Efren, Jem and Shayne) Jan. 19-23. I'm so eggzited!!! I've never been to Ilocos, but I've always wanted to go. Everything's set. Hotel reservations confirmed and fully paid. Flight booked and confirmed. Airport transfers arranged and fully paid. Now I have to get to work on my itinerary... So far, my general plan is to do Laoag on the 20th, Vigan on the 21st, Pagudpud on the 22nd, and the remainder of the places near Laoag on the 23rd, since my flight doesn't leave until 9:30pm anyway. Anyone have any suggestions?
