I have checked the weather forecast and trains for next Sunday and it is not looking great for this trip.
It is predicted to be a wet day plus the only trains from Orpington are going into Victoria which wouldn't be a good starting point I feel.
I'm suggesting a postponement for the time being. I'm off to Belgium/France twice next month but might be alright to do either Sunday 5th or 26th June. I'm keeping it a Sunday in the hope some of those unable to make a weekday due to work commitments can join in.
We have all summer to get this going and remember it doesn't have to be London if others have any suggestions.
