The shuttles that they use only seat about 4-5 couples. So worse comes to worse, there will be one other couple in the van with you. They don't hire those huge buses. They are more like over sized mini-vans.
Also, the couple that is meeting you at the lounge actually will not be able to meet you at the lounge as that is a secure area that can not be reached after a person has left the airport. They will be able to tell a guard that they are there and waiting for transport, but they won't be able to join you in the lounge.
