Bognor away - Trains

Folks, due to ongoing strike action on Southern it's likely that there will be no direct train service to Bognor on 14th January.  I'm checking alternatives but it's not looking positive at the moment :-(   The best I can do at the mo is Havant then an hour on a bus!  You local peeps may be best off on the coach but if anyone fancies picking me up from Colchester please yell!!!
