If you are lucky enough to get a ticket, make sure you arrive at check-in for the trip at least 20 minutes early. The organisation is like a well-oiled machine, but offers zero latitude for latecomers. Not there in time to get your sticker, badge and have your name checked off, too bad. Thats it - nada - you were late, you missed your chance, get up early again tomorrow. No point in arguing with the officious official. He has 1318 others to herd through and he's heard all the excuses for being late before.

Be warned that the visibility from the sky deck can be pretty poor, depending on the humidity and whether it is about to rain, is raining or has just rained. It's still worth the experience though for the ability to wear 70s retro style 3D glasses while watching the Petronas promo film before the trip up!
