Stayed at Lagen Island a couple of years back. We had full board meals, all the activities the island had to offer (island hopping, diving, night fishing, windsurfing, kayaking and hiking) and the plane fare were all inclusive. I believe we paid about $400 a person for Lagen Island.
Nandun pa nga si Bea Zobel and her 3 kids during the time we were there. They went there by their own chartered plane and stayed at the more expensive island houses.
