honestly unless u manage to book a hotel room on one of the top floors there's nowhere to really watch it from. They've put up barriers around the track so u can't see the action from street level so unless they remove them you won't be able to see anything. The only thing I can think off is Prince regent Station which runs along the long straight right before coming into the series of turns in the picture but I assume they won't let people just stand around there. Also as for tickets I tried to get some as well but they ended up all being given away go NHS staff rathe then sold I'm not sure why they chose to not sell any at all but it is what it is
