Thanks Paul,
I've been working (cutting & pasting from the interweb) on this all afternoon. This is what I have: (looks just like yours)
Code:
Sub Main()
Dim i As Long
Dim tgf As String
With Application.FileDialog(msoFileDialogFolderPicker)
.AllowMultiSelect = False
.Title = "Select Folder for..."
.Show
tgf = .SelectedItems(1)
End With
MsgBox tgf
Dim vrtSelectedItem As Variant
With Application.FileDialog(msoFileDialogFilePicker)
.AllowMultiSelect = True
If .Show = -1 Then
For Each vrtSelectedItem In .SelectedItems
Documents.Open FileName:=vrtSelectedItem
With Dialogs(wdDialogFileSaveAs)
.Format = wdFormatPDF
Options.DefaultFilePath(wdDocumentsPath) = tgf
.Show
ActiveDocument.Close
End With
Next
Else
End If
End With
Shell "C:\program files (x86)\adobe\acrobat 11.0\acrobat\acrobat.exe", vbNormalFocus
End Sub
And it mostly works... mostly

It doesn't keep the folder path as initially selected. I can see I've reused the .SelectedItems, but I have no clue how to manage this. I would like some advice on this.
I need to work out how to SaveAs silently unless the file already exists, but I'll keeping digging and start a new thread when I give up in frustration.
Regards from an overcast and slightly rainy Queensland (the locals are running around crying "the sky is falling, the sky is falling...)
