We have a detailed map of SXM that we ordered via mail but I've heard it's available on the Boardwalk in Philipsburg.

I too am not a computer genius but I use maps.google.com write in the place name and location comes up very clearly, then we check our map. You can also enter address of where you're staying then the name of place you'd like to go (whether or not you know the exact address) and you get your answer as to distance.

If you tell TTOL where you're staying someone can tell you what's nearby.
