September 2025? As in almost 2 years time? Things may well change between now and then.
Anyway, I recently witnessed someone in a similar situation and the lounge attendant said something like "and how will you be entering today?" to the 3rd person, and then clarified, to some confused looks, that only 1 guest was permitted. There was then a few "no no, you go in" exchanged between them, and then ultimately none of them went in.
I wanted to say one of them was actually my guest, but felt like this particular lounge attendant would have seen through it and not allowed that.
