ILOCOS TRIP 3D2N

Hello! May I ask if what will be our itinerary for our 3 days 2 nights trip in Ilocos? I am confused if we will start from Ilocos Norte going to South or vice versa? We are from Nueva Ecija and I am planning to have a DIY plan since we are a group 6 pax with 1 child and would love to go on a roadtrip. Thank you!
