Parking near London excel

Am loading into London excel Sunday morning. After parking for tomorrow afternoon/evening onwards. Not been for a long time so my old spots might not be there anymore

Got river road barking can park there. Seen trucks there in the past haven’t done it myself though.
Plus have be carefull these days if you have to pay any congestion zone clean air. Zones…your be paying them twice.
Once for parking up for night and once for next day. As charges usually last untill midnight of the day you enter said zone.
