After the Danes sent a new benchmark for logistical incompetency in Copenhagen - less couldn't organise a piss up in a brewery, more couldn't organise an international summit in one of the world's richest cities - you would have thought a bit more thought would have gone into the organisation of the Cancun Summit.
Not so, according to a rather fractious sounding John Vidal at the Guardian:
"The main conference centre is at the mighty Moon Palace resort, which is 35km away from most hotels and actually comprises three separate monstrous complexes. To get to the Moon, people must take off in a bus, travel 40km, go through a security check, and then take another bus a further 10km. When on the Moon, it is nearly a mile between the press centre and the hall where the press conferences take place, and a further mile or so between there and where government delegations hang out.
Add to this intermittent internet access, one-hour traffic jams, a boiling sun and freezing aircon, and you have all the elements of a PR disaster with delegates despairing and lost journos rushing around."
Suddenly London in the snow doesn't seem so bad.
Although you do start to wonder if the UN will ever learn how to hold one of these jamborees properly, particularly give we look set to be having them for years to come.
First up, don't hold it anywhere too glamorous, otherwise you will end up with a glut of headlines similar to this beauty from the ever-charming Daily Mail: "Coalition spends £1.2m on climate change talks since election - not including Cancun"
Secondly, either make sure there is enough space for everyone to fit in, or alternatively stop inviting so many people.
Thirdly, sort out the transport links. If a country can host a successful World Cup they should be able to deal with a few thousand diplomats - after all the chances of hooliganism are about the same for both.
Finally, and most importantly, stop hosting it in December. It may be disgracefully western-centric to even make this point, but at this time of year no one is watching. Everyone is gritting their teeth and trying to get through to the end of another 12 months. How many of the officials in Cancun secretly just want to get home for their annual holidays.
The Sceptic Tank has checked the diary and come up with the perfect answer - apparently the National Exhibition Centre in Birmingham is available next September. Its cavernous, its near the airport, and its anything but glamorous.
