What do you want to see? You can take a ferry from Cebu (Malapascua island in the north and Moalboal in the south) to Bohol (Tagbilaran and Panglao island) to Dumaguete (Dauin and Apo island) to Siquijor about 3-4 days each place but there are a lot to see I have not mentioned. El Nido in Palawan is worth one week of stay and Coron island is another week, like 2 of the best in the PH. Siargao is more on surfing. Boracay island we did 4 days with friends. Each island in the Philippines has many things to offer.
