Tentseller, thanks -- that is sensible advice.
Chrome25, we are thinking about that. Just seems like a shame with our multiple lounge entitlements (those discussed above as well as airline elite status) -- very very close to all allowed to access, multiple ways, without charge. Separately, I'm not sure how much lounge access actually is worth to us -- to kids, who hardly eat and who enjoy running around the terminal at least as much as going to a lounge. USD10/person sounds low but it's all about the context.
