Beach bums and divers will want to spend the entire week in the Visayas, either island hopping or just relaxing in a resort on Boracay, Cebu, Bohol, or Negros. If you prefer mountains and hill tribes, spend 2 days exploring the rice terraces around Banaue, 2 days in Sagada, and 1 night in Baguio. If possible take a 1-day detour to Vigan before heading back to Manila for 1-2 days.
