I have resisted doing this, just and I mean just incase you have to get parked....
Depending on where you come out, Sammies etc....Follow the below I think pictures are better than words on this...Basically turn right from Departures, goto the end of the road and a TIGHT left (stay in your right lane) to get over Chelsea bridge, then ALL the way to the Roundabout with a garage on your left...NOT under the arch but were I have highlighted, then ahead till you see the Queen Victoria pub and a left to the end past Babe Station then right into depot and park next to other coaches by reversing again back wall....The Yard man may come out and ask what time you are leaving...I used to give myself about 15 minutes to return, but in RUSH hour it could take 45 minutes...WHY WE DO NOT USE abellio...BUT if no other option exists to park....
ANOTHER WAY to Approach Chelsea Bridge is from Eaton Square...Instead of taking the final Left where the trees appear, to go back into Arrivals, go straight ahead....This may be the best option to avoid the TIGHT left
ONE point to NOTE when returning WATCH and I mean WATCH the high curbs under the arches/bridges...You'll see them going in so split your lanes, if you can't WAIT till you can......
VERY TIGHT LEFT
