Hello! I have to make a trip to Portugal this summer and figured "why not leave earlier and make it a road trip?". Just finished plotting a route, looking forward to receiving your feedback. Any suggestions/remarks are welcome! This is the link with the route: https://goo.gl/maps/LDBSbRmWznN2
By the way, I'm new here! Nice meeting you all!
First off, welcome to TP.
I've looked at your map and honestly, you're covering wayyyy too much ground in 15 days unless you don't really intend on seeing any of the places along the way. You pass through some great cities, etc. but if you don't have the opportunity to explore them, it begs the question as to whether you've actually seen them or not. I'd suggest picking a few places to spend a few days and visit and travel a shorter distance. Or plan a couple of long travel days with longer stops in key cities / towns. What is it that you want to see / are looking for out of your trip? And what is it that you are interested in? When are you going as driving conditions and weather vary significantly across Europe and this may be something to consider during your planning stages.
