It depends on your budget and the number of people but I would look at Samal Island for a conference and seminar location in the Davao area.
Samal Island: is less than one hour from Davao International Airport; weather is predictable year round (no typhoons); a number of beach resorts have meeting, conference and seminar location facilities.
At the top end of the budget scale you could try the
Pearl Farm Beach Resort, one of the World's best beach resort locations on the recently voted Best Vacation Island of Samal
If you are looking for a more economic but well catered meeting, conference and seminar location then check out the
Punta Del Sol Beach Resort on Samal Island = relaxing and tranquil with accommodations of all levels, including camping - always a good team building exercise.
If you would alternatively consider a city conference and seminar location then there is always the Marco Polo Hotel in downtown Davao City - pricey but with a view over the entire city and they can arrange team building away-trips to Samal Island.
