Cancun was not a surprise. Nor was it a failure. This much is easy to say.
But was it a success? This is a more difficult question. I used to have an irritating friend. Every time you made a strong, implausibly simple claim – something like “Cancun was a success” – he would reply “Compared to what?” It was a pedantic device, but it worked well enough. It made you think, which, I suppose, is why it was irritating.
