Much appreciated once again - I think my preferred option is to drive down to HI Kingston from Manchester.

Then either park up at hotel HI Kingston and get a return taxi to Twickenham

or

drive to and park up at Twickenham returning to HI Kingston thereafter.
Would anyone know generally how parking is at Twickenham? Is it one of those stadiums where parking is straight forward with an easy get away afterwards or an absolute nightmare?

May switch hotels later if Pointbreaks has something interesting at the time
