Go see the festival in San Fernando, Pampanga, where a few volunteers reenact the crucifixion by themselves being nailed to the cross.

I haven't checked it out mainly because of fear of traveling around during such a heavy volume time for locals to travel.

Have been to Boracay twice but it's probably a lot more built up now. Small and very fragile place, but beautiful if they don't ruin it. Also went to Sabang, Puerto Princesa and Dos Palmas in Palawan (before the attack) and all that was quite nice. El Nido and islands off the north end are likely even more scenic, but air access is a tad pricey and low-volume. Malaria and access to medical care also used to be issues for that area, but the situation has probably improved in recent years.

Cebu has historic sites and is more compact and manageable than Manila, and Bohol has both some beaches and the Chocolate Hills. Have also been to Bantayan, where locals are friendly but the beach is no great shakes.

Boracay is the closest to a fly-in/fly-out type of beach like Thais have with Phuket or Samui. Some of the other better natural attractions take effort to get to.
