Olympics 2012 city host

I have seen all of the proposals that were sent to me some days ago about the host of the 2012 Olympic Games. I highly advise that we better choose city B as the host of the next Olympic Games. There are several reasons to choose city B rather than city A or C:
The temperature in city B was cool, so participants will not get tired so easily.
City B has the most venues (19) with total capacity 165,000.

The transportation system is also the best. There will be state-of-the-art Urban Rapid Transit System under construction (would be complete in 2008), there is also an international airport there.
City B also has the most place for people to stay, about 90,000 rooms within radius of 50km.
The security is relatively secure

From these reasons, I highly advise the committee to choose city B as the next host.
