Looks like a lot of people can still get there for the saturday. Suspect they could cheese more off by moving it to another date at such late notice than those that can't get there for the original date? Not ideal either way though.
I think I’ve got this sorted - sort of! Stay at my daughter’s in South Croydon sick, she’ll drive us down, she, me and my grandson early doors for the park and ride. Stop for late breakfast/brunch beforehand. Hit the P&R early and get to the Amex.
I would rather that the whole thing was called off and rearranged for later on in the season but at least our contingency plan is in place.
