with 1.5 million people...its really difficult. best way to go about it is to exchange hotel information and discuss a meeting spot when we are there. berlin is like a shorter version of manhattan...a beautiful city filled with as many little nooks and crannies as manhattan. When you get there the weekend of the loveparade it will feel like a dance music convention..everywhere you turn you will hear dance music coming from..bars,shops,plazas..even mcdonalds in will be playing some type of dance music. if i was to pick a place for a meetup it would be the berlin zoo. the train stop (zooligarten) is fairly close...and the walk to the center of the loveparade is a mere 5 minutes away.
