Magic Oceans Dive Resort at Anda on Bohol in the Philippines is asking this leading question, because for four months from the start of June it has a “buddy offer” whereby a second diver sharing one of its bungalows dives for free.

Also, there is no single surcharge for lone travellers during that time.

Dive Worldwide offers year-round Visayas combination trips that also take in Magic Oceans and its sister-resort Magic Island at Moalboal on Cebu – a 15-day itinerary costs from £2145pp including flights.
