I've actually done this a few times, last time being Halloween last year. I would not describe it as "thrilling" but it is a helluva lot of fun! Particularly if you do it on a night with a big crowd below and the light show running - it's quite a unique feeling! The hardest part for many is stepping off the platform - just look upwards at the light show canopy if the height or open space below bothers you as you step off.
