There's no need to add space before closing quote if path doesn't contain trailing backslash, so following command should work:
robocopy "C:\Source Path" "C:\Destination Path" /option1 /option2...
But, following will not work:
robocopy "C:\Source Path\" "C:\Destination Path\" /option1 /option2...
This is due to the escaping issue that is described here:
The \ escape can cause problems with quoted directory paths that contain a trailing backslash because the closing quote " at the end of the line will be escaped \".
