Thanks for the code worked perfectly. I'm not a coder at all (generally can never get these things to work) but this was easy to use and simply just a copy and paste. Just indent the "lyt.exportToPDF(f"C:\Temp\{lyt.name}.pdf", 150, "BEST", True, "ADAPTIVE", True, "LAYERS_ONLY", True, 80, False, False, False)" line.
Copying and pasting the elements works too but it's not really conducive to a larger number of layout views. I often have over 30 maps per project and a time limit due to cost to get these done.
