Hello Adan. Many thanks, I think this is what I need.
All our points are stored in a database, as you can see here (click in the map menu), this is only one hotel of many, but all the lat and log are in the database, and we also have the lat long of the city. http://www.southerncostarica.biz/Dominical/cat-hotels/Hotel-Domilocos/227/ <http://www.southerncostarica.biz/Dominical/cat-hotels/Hotel-Domilocos/227/>We have to test and try, but this is a good starting point.
