No worry about the ride time.
After all the it's gonna be on a SVX.
Regarding your girlfriend objections I am sure I will come as a good surprise.
Will she feel better if I post a picture of my two kids and my wife so she can see how much a Family guy I am?
Just joking.
Anyway my plan, although a bit early to confirm, would be something like the following two options:
#1 - One day option - Meeting in Spain (O Grove) on Monday morning and then have a cruising trip until Portugal to show you one or two nice places and then go back at the end of the day.
#2 - Two days option - Meeting in Spain as option #1 but coming down to show you my city (Porto), spend the night there, continue the sightseeing in Porto and then bringing you home again by the end of the second day.
No rush, just having a nice time and cultural interchange.
All theses options will include nice lunches and/or dinners with warm red wine or ice cold beer.
Let me know which one you are more inclined to.
