Since Dingalan is a relatively new beach/tourism destination, it still lacks facilities. For your bodily functions, there are crude toilets (pail + bucket). For showers, you'd have to shower out in the open and pump your own water from this artesian well. So it's only for backpacker types and not Dillinger or Landreth tastes.
I didn't see a single white foreigner in the place, only locals were there.
As for our food, included in the tour package was lunch (boodle fight style), consisting of small crabs, mussels (tahong), grilled milkfish (bangus), adobo squid, grilled liempo (pork belly), eggplant, watermelon & unlimited rice.
