Wembley event parking

[noimnotbutyoushouldseeyourfaces]

Hi all.
I'm going to an event at Wembley on a Thursday, and have a hotel room booked there overnight.

I've paid £40 for event day parking but won't be moving my car until the Friday. If I book the Friday at another £40 am
I covered? Or would I have to 'exit' and re enter?

There's no number to call and ask!

you'd be better off parking at a tube station
on the outskirts like Edgware.
Cheaper parking and easier to get to. Or just using the train there and back
the next day

I've already booked a hotel at Wembley, so need to park there!
