How many days do you really need in Philippines?

For a first visit, 8 days is a comfortable amount for Philippines — enough to hit the highlights (Palawan (El Nido, Coron) and Boracay's White Beach) without rushing. You can do it in fewer if you focus on one area, but you'll be moving fast. If you can add a couple of days, you'll have room to slow down and enjoy it properly.
