Hi
I'm new to this forum but I hope this helps you.
I have just done a club europe return MAN - TXL (Berlin) yesterday on miles. No problem with lounge access at all stations.
I assume you booked club/business edi - fco or VV?
If yes, then check your tickets in manage my booking you should see UK Business or/ C for the domestic legs + invitation to use the lounges.
Simply present your boarding cards (printed online/or at the airport (2) in your case) at whichever lounge and enjoy the trip
