Hiya Steve r. It's good you've got lots of experience to share in the future. If you happen to be in the Central Visayas in the Philippines...drop by Cebu where u can also visit the hot diving spots in Malapascua Island in the North and Moalboal in the South. There's a lot of PADI english divers too.
Malapascua Islandis the only place in the world where you can dive with the magnificent thresher sharks every day. Manta Rays can be seen as well plus it's a quiet island. My husband loves it there.
In Moalboal
