Google Maps – Number of Locations Increase

Hello. I’d like to add more than 10 locations to a map. I have about 25 to 30 that need to be accounted for. Can this be achieved? I ask because I was not able to use the WP Google Maps plugin as it had conflicts with the plugins that ship with Highend. Please allow me to increase to more than 10 locations until I can locate a better, non-conflicting plugin for maps. Thanks.
