The cave itself wasn't very special in my opinion. A lot of bright purple LED lights, which makes it possible to see far into the cage, but also disturbs the natural darkness and 'mystery' of a cave. The view after you've exited the cage is great though, definitely worth the trouble...
In this case I would say no, but taking into the account the option to store more than one season of data and maybe to cover more than one location in a multi-airport situation, maybe yes ! Velocity Do150.000attributes a day qualify for big data velocity ?
