I was at K in B thursday. The only time slot I had with a friend. It was half full, so maybe 400-500 people. All ages, more older ones. Still I saw at least 10-20 interesting ladies. Some nice tatoos, no piercings. About half shaved. I had a nice day. No jackpot, Easter weekend was probably better. But no dissapointment either. I went 18-22h, the later the better. It is also nice to see the ladies putting on their underwear at closing time.
I bought the tickets online, the blue vending machine at the entrance scanned my ticket and gave me my chip bracelet. No qeueing, we just walked in directly.
BTW, public transport is clean and cheap. Airport to K is around 30 min. for 5€ (ABC ticket). Check for BER to Kristallbad on vbb.de. So why not fly, relax, and then go to your hotel.
