I think they put a lot unseen work into drainage and hardening the area every year, so I don't think we'd get anything apocalyptic again (touch wood. Of course, when mother nature gets really angry you're not going to beat her, but I reckon the chances of that are low).
However, I do think a good portion of the entitled rich youth that make up the numbers would pack up and go as soon as they discovered a pinhole leak in their tent.
