I do this in conjunction with Google Earth.
A lot of destinations are not there and you have to zoom into the map to find the right spot to make a waypoint. I recently loaded the program onto my older MAC (I had to upgrade the OS to make it work) and I am here to say, WHAT a DIFFERENCE. We set one with the hotels/B&B's and the other with the entire itinerary. We always bring two devices just in case.
To date and the maps were always correct and led us exactly to where we needed to be. We have planned trips to Ireland, Germany, England, Scotland using BaseCamp. I used to use my dell laptop to plan our trips and the program took for ever to load and crashed during planning multiple times in an hour.
It is a great tool to load our international vacation trips into our Garmin GPS. My wife and I have used BaseCamp for several years.
