Just took a bit of a more careful look at the website and I probably mistook some other voucher offered to golds as being a lounge voucher... To my defense they do offer various vouchers. Silvers get 4x lounge access, then there are the 2x (S) and 4x (G) seat upgrades etc. I probably misread either one... Sorry
(maybe you can upgrade the family and get them even more psyched
)
