I'm a regular visit to Germany, but have never been on 'the other side' of a spa, where clothes are very much verboten!
What's the protocol? Are you allowed to wear a bathing robe/towel as you walk around the pool, and then slip it off immediately before entering the water?
My main concern, being British and a bit shy(!), is thoughts of walking around the side of the pools with everything hanging out! I presume it's a little more subtle than that?
We will only have four hours there. Is it worth visiting the non-clothed section at Erding? We love water slides and general 'themed' swimming. Is there anything spectacular in the nude section that we cannot have in the admittedly busier clothed section?
