Hi guys,
In case you decide to stay in ScubaWorld Punta Engano (ride beside hilton and shangrila right in between I think in fact), its a pretty basic accomodation and food but rooms are airconditioned and cheap. I believe its around PHP1000 to PHP1500 per night per room depending on the what you get. The twin sharing room or the family room with 3 beds. The facility is now an IDC center. It has the classrooms and a pool. It also offers Nitrox if I am not mistaken. From there to the airport is about a ten or less minutes ride. Just an fyi.
