Where would you go? What would you do?
I like planning for non existent emergencies and it's a bit windy out.
I'd have to leave the caravan I'm currently staying in and find a brick building, conveniently enough that's a local pub. I would go to the cellar with bottle of pop and crisps.
The alternative is the onsite amusements but I think the building is flimsy and there'd be too many people there to be comfortable.
