Do you native readers think that either "around" or "about" could be dropped from "around about noon"?We no longer have one without the other, and on Wednesday around about noon, the 2008 destination will be announced.
"Around about" is tautology but frequently used. You could drop either, but I would say that retaining "around" would be better. With "about" I would probably put "at" in front of it.
...on Wednesday, at about noon...
...on Wednesday, around noon...
...around noon on Wednesday...
So, there is some redundancy in "around about".
