When I travel overseas I do. I used the Virgin one in LA, and it was such a wonderful break in the trip. I had a shower, got great food, used the internet and had a nap before going on for the second leg of my journey. It was a wonderful experience and made the trip much more bearable.
I have done and its a fab experience, and has made for an enjoyable travel experience. Now that I've got kids our airport time is spent watching planes and expending energy so my airport lounge days are on hiatus.
Fairly often. I had a voucher left to enjoy The Qantas Club at Melbourne to head back home to Sydney despite flying economy class. When you fly business class, lounge access is yours too. It depends on how much time you have left to enjoy it.
Ah yes! That little piece of quiet & restfulness. Fresh snacks, cold drinks, hot coffee or tea. Away from screaming, uncontrolled kids'.
And clean facilities' for the use of, including SHOWERS!
Qantas Club for me. Been going in there since its' inception.
Used to go to Ansett's 'Golden Wing Lounge'. Sadly both are no more.
