I totally understand wanting to stay in Dumaguete. But if you plan on traveling throughout the Philippine Islands, Dumaguete might not be the best place logistically. If you want to fly to explore, you are stuck going to Cebu or Manila first. Every time. If you want to use the extensive ferry routes, Dumaguete is not much of a hub. Cebu would be a port with many more choices....probably by a factor of 10x, or more.
Dumaguete, and its environs, is a great place to be. But if you want to go somewhere else, you can't get there from here. (With few exceptions.)
