That is good, you were able to learn Tagalog. I guess if you can do it, I can do it too. Did you pick up a lot by watching TV, or simply by being exposed to it all the time? When you go to Palawan, you will be exposed to it again, unless they speak something other than Tagalog there.
Full exposure. I lived on the local economy while I was there so I was in the markets haggling, in the bars drinking, in the movie theatres, etc.
