Hi!
It’s not exactly an issue, but a solution for the fullwidth map I was looking for some months ago https://kriesi.at/support/topic/full-width-google-maps/. I finally used the following plugin for responsive full width Google Maps http://yava.ro/ and they have a nice support that helped to set up the PHP template for full width map for Enfold Theme, as it can be seen on http://www.ksuforumonthecity.com/madrid-itinerary/
Hope it will be useful to someone else too :)
Cheers,
Anne-Sophie
