I would advise to learn couple dancing as: * Zouk (and if you are already doing street style dance, you will love black zouk) * Bachata (there are so many Bachata dancers around the world, that any country or trip you do, you can go into Bachata socials and make local friends all over the world) * Tango (it is the hardest dance to learn, but it has the best connection of all)

And definetly go into dance congresses. There are multiple dance congresses on Europe, but if you can go to some of the best dance congresses like zoukmx or into brazilian zouk congresses during January in Rio de Janeiro, it will be a life experience.
