Vote! Where should the Travellers go after the Philippines?

When the travellers were in the Philippines, they made friends with a boy called Nonoy.  His dad gave them a coconut for the journey ahead.  As they were leaving Manila (the capital city), the map began to glow.  They had coconuts on it and the words, "I follow the path of human civilization with the tides and ebbs"

What does this clue mean? Where should they go next?
