Thank you all for your responses! They flew out last evening to London for the weekend then on to Edinburgh. They did pack warm and waterproof clothing as well as some for inside the convention centre ( i.e. heels, dresses etc.).

Those in Edinburgh be warned the city may not be safe from the roving gangs of oncology nurses! For your own protection if you should encounter any of these roving oncology nurses they can often be tamed with a pint or three! if your kilted then run, run as far and as fast as your wee legs can take you! LOL!
