Good luck for the residentials tomorrow.
If anyone is travelling by train, please allow plenty of time and check with southern rail how the trains are running. There isn't a train between Horsham and Dorking due to a landslide on Christmas Eve, and there is a rail replacement service for the next three weeks. The line through Gatwick has also had bus services operating on parts of it due to engineering works, fallen trees and a land slip but the areas affected seem to frequently change as the problems clear, but I have just read on the Horsham Facebook page that they are expecting the engineering works to be completed today.
Best wishes, and good luck with the residentials xx
