Yes AN at CN is very discreet
Nudity at CN is only permitted at the AN section of the beach and in the water in front of that section. The loungers are divided from the rest of the resort with a large privacy hedge. There may be some toplessness on the rest of the beach but never an issue as that's usually quite discreet as well..
If its offensive the beach is about 1000 ft long and very deep so you can easily move away. In fact its never been very crowded when we go in August.
Toplessness is not permitted at the pools.
At CN the AN is so discreet unless you go looking you may never know its there. Again when we go in August it seems there are only a few couples at the AN section.
No worries about getting a view if you dont want to, only piece of advice is avoid buildings 6 and 9, especially 9.. from the level 2 and 3 balconies you might get a glimpse of the AN section. From the ground you wouldn't see past the hedge
