another thing - they only sell tickets for specific tours now - so you can buy your ticket (which is usually 90 Minutes later) so you have enough time to walk up, hang out or whatever. in the past you just bought a ticket and got in the line. especially in the high season you sometimes waited for hours. but today everything is relaxed. i think you can also prebook online here
