Parking on a Sunday Kensington Olympia

[lost in espace]

I am being dragged along to the final of some Sky dance program on Sunday at midday. I need to park around Kensington Olympia, I am aware that pay an display meters are free but I am going to have a nightmare parking?

It may be easier for me to take the underground, but its going to take a whole lot longer!

most of that area is free on a sunday, all the side roads behind Olympia are free on weekend.
Traffic should be ok plenty of options to get out of there if A4 is jammed go A40.
