One cannot compare Manila to anywhere else in the Philippines. Crime is bad in Manila. Most things are bad in Manila for that matter! lol (Except the night-life...it's one heck of a party town, so maybe not a bad choice for a single guy!)
Dumaguete is MUCH MUCH safer than Manila or even Cebu or AC for that matter. However, I would say that Thailand is generally much safer and more peaceful than the Philippines. (At least in my experience.) Never been to Costa Rica, but my friend who lives there tells me theft is big problem.
I suggest you tour around and spend some time in different locations in all three before you settle on a spot. Thailand is cheaper (unless you like to go out and drink a lot), safer and has much better food; the diving and IMHO girls are better in the Phils...along with the smaller language barrier. But, I really like both! |
