You could also try and take a look at IGACOS (Island Garden City of Samal). It's an island with lots of beautiful beaches, waterfalls and batcaves (No, Batman isn't there
).
The Island is just a few minutes boat ride (cars can take the barges) to Davao City (The hometown of the current President of the Philippines, Rodrigo R. Duterte).
And since tourism is the island's main source of revenue, of course, a good internet connection is available.
Davao City and IGACOS are on Mindanao, a group of Islands located in the Southern part of the Philippines.
Also, from what I've heard, plans on having an entire bridge connecting the Island and Davao City are already in the works.
