Looking for someone to go on a road trip with me.

Hi, I'm 19 and looking for a companion for about 14 days in July or August 2018. This would be my first road trip, so I'm a complete beginner :). My planned road trip was with my car (sedan) from Germany, Paris, Monaco, Marseille, Barcelona, possibly even further away or Germany, Lake Garda, Venice, Pisa, Rome, then by ferry to Greece and up towards Croatia and back to Germany. I planned to sleep in a tent on a campsite, wild camping, and/or a few days in a hotel. I'm also open to other plans and destinations, as long as it's a road trip. I'm also interested in going to the Baltic Sea for 3-4 days or even just a weekend before that in 2018. If you live far away, we'll surely find a solution.
