Hi there, Jackson and Kris, and thanks guys for your very kind responses.
Jackson, you ask good sensible questions, but I feel we have inadequate experience now to respond very well to your questions. My wife and I are mainly into extended family life and so now tend to avoid places and activities that are normal for holiday makers.
Sorry mate, can't help you much. However of course we have visited the popular visitor spots years ago, like most everyone does, and these are all well worth-while of course. Such places include the Underground River, (the main attraction), Bakers hill, Puerto Cathedral, the prison farm, the crocodile farm, CocoLoco, El Nido, and Coron etc.
We are in Australia currently, otherwise I might suggest meeting up with you guys and showing you around a bit. However, it really is a lovely place, and we are sure you will enjoy your stay.
And Kris, you have truly wonderful aspirations indeed, and we hope you find a way to make it happen my friend. One idea you might like is that there exists there a number of special schools for variously disabled kiddies. We have met some of the volunteers and they are indeed wonderful people. I'm sure you could do a power of good with any such involvement in the area. The variously disabled children are really quite adorable.
Good on you Kris for wanting to help in some way. Any time you spent on this beautiful island and helping children or anyone in need in any such way would indeed certainly be memorable time very well-spent. They are always looking for volunteers. Anyway, just a thought my friend.
Cheers gents!
