Heading from US to Italy, Anything To Do?

Greetings community, my first post.

I have a Garmin 64st and will be taking it with me to Florence and Rome, Italy, in a few months (from the US).

I was curious if there is anything to be done in either BaseCamp or even the 64st in advance of that trip. I have not used it outside the US so unsure if I should plot or plan anything on the device or BaseCamp before heading out.

I do plan on trying to Geocache out there, so I know I should download the caches in advance (but closer to the trip in case they go dormant), but as for Garmin software, not sure.

Any suggestions gladly welcome.
