you are going to need a mix of 11 pax in UC with no guests of their own and AU with no guests of their own.
Highly unlikely.
BTW many people on here will only guest in people they know personally or who have a record of posting on v-flyer. They might be willing to guest you but not one of your friends.
I knew the request with ultra cheeky and a massive long shot.
We were in the No1 lounge until a random email on Thursday cancelled the booking. I am yet to find out what we done that's bad enough to be kicked out before arrival
