I will be arriving at the main Prague train station, and I will be meeting somebody at the Burger King at the Arrival Hall to pick me up. I read online that the Prague train station is confusing, and it lacks signs once you exit the train and onto the platform. (My first thought was to follow the crowd at that time, but it is best to ask here instead). Can anyone direct me where to go? (I will have multiple luggage, so I will need an elevator).
