Two types of information on the same map

Hello,

How can I do multiple integration on the same map?
I'd like to display several maps, each containing :

1. an itinerary with few steps (each step is detailed in an gmap item)
2. some local information (hotels, activities) each piece of information having it's own gmap item

The point 2 will be the same for all maps.
In fact I need to be able to create a menu item calling two categories.
I don't see how it is possible with GMapFP

Thanks for your help
