My first weekend in the Philippines as a volunteer was spent on Bantayan Island with an overnight stay at Beach Placid Resort with three others. Rooms were affordable, we had two cottages each with a bed for two. The rooms are small but has everything you need including hot water. Wifi was not available in the rooms though.
The staff is nice and while the restaurant is slow to serve your food, the food is really nice.
They'll also arrange a 1-hour full body massage in your room for only P300!!! Cheapest massage I had in the Philippines (although the best was in Bohol).
