I want to say "go away from this place" to a number of people. I have two options:

Daqvamvo' yIghoS

or

Daqvammo' peghoS

Which is the right one ?

If someone knows, please tell me, but don't start writing crap like "don't use {ghoS}", in order to avoid answering the actual question.

The object of ghoS is a locative, so it probably can't take an ablative as its object. Therefore the correct sentence would be Daqvamvo' peghoS.
