I need to move hundreds of vertices to and exact x,y location. I know I can double click a single vertex and select "move to" but I might as well just drag and drop to the new location, is there a way to move multiple all at one?
If they are going to maintain their relative position to one another just select them all. You can then drag all of them. Additionally, there will be a feint 'x' in the middle of the selection, this is a snapping handle. If you mouse over it and hit the control key you can move the handle to a specific spot and use it as the snap point while moving everything.
Okay. You have an existing feature class and a list of where the features should be XY wise, right? Is there an identifier in your XY information that could be used to associate the existing feature class to the correct positions? You could bring the correct positions into ArcMap using Add XY Layer, joint the existing FC to it and then export it as a new FC.
