Thursday at 18:00 or later in Maremagnum? Which bar (the building is big). Geeky shirts will help finding people. At least for Thursday Maremagnum is better since it's closer to the center (Port Olímpic is exactly in the other side of the city for those staying near Citilab. Barcelona is not like London, but still if people are just arriving and finding themselves... the end of the Rambles is always easier. Owners of cameras, tablets and nicel looking mobiles: Barcelona is a city very good for your personal safety but the safety of your tech belongings is another story specially in the city center and specially if you show them off. Mardy, you're from Italy so I believe you know perfectly what I mean.
