I'll be arriving at ATL around 9am and have a 4:30pm flight to FRA on a weekday. Is it worth the $50 to be in the Sky Club at Terminal E? First, can I assume that the Sky Club is inside security so no need to have to endure it? If you had essentially ~6+ hours at ATL, would you buy the pass? I would be buying it at the Sky Club; I assume that's not a problem. Thanks.
