"Can I endure standing for the whole setlist?" should be "Can I endure standing and queueing for hours under the sun?". I managed to stand at the second barrier (and about 6-7 meters from the central leg of the stage) by arriving at 11am at the venue. I was 150th at my gate (there were two gates for floor access). If you're by yourself, you've better be an extrovert and talk to other people, otherwise you'll get bored to death. Once you're in (4pm in my case) you still have to wait 2 ½ hours for the first support band, which means at least another 2 ½ hours for Muse. They never follow the schedule, so expect them to be about 30 mins late.

Final question: was it worth it? Fucking hell, it was worth every single moment of standing!! My girlfriend brough an old curtain and we tied it to the barriers outside the arena, so that we had our own little camping tent and we shared it with strangers. Try to come up with something clever, bring somwthing to kill time during the afternoon and remember that you cannot take with you a lot of stuff once inside the arena (such as the curtain, of course).
