I had this issue at the *G lounge in MUC back in September, I was *G and my wife and I got in, but my daughter could not.. When I asked about purchasing "access vouchers" or access to the Sentator Lounge they had no idea what I was talking about. Previous to this a couple of people on here had said you could buy access at the lounge, but I guess it wasn't available at the time we were there? The lounge was far from busy. LH is not very clear about a lot of things, unlike UA.
