Donauinsel - local information please
I am planning to visit Wien in July, and was thinking of going to the Donauinsel to enjoy the sun (I hope!) in a natural way - my first time like this! I know there are 2 FKK areas ... north and south of the island - which one is better? And, of course, what kind of 'fun' is there? - is it different for each area or is one better to meet with other people? Any local knowledge would be very welcome. Thank you.
