I guess pretty much every town you can be safe outside PZ (in non-pvp servers, ofc).
Why do I think that? Because, even tho creatures can be lured / raids appear, you can always go to the underground of a building, or +1, +2, +3, of an apartment building, etc...
You don't have to stay AFK in front of the DP, where you are the most exposed, if you are anywhere outside the surface, you are 99% safe.
(the 1% unsafe is because in venore, feverished citizens may respawn in some buildings in places that are not surface)
