You do but it’s no benefit for missing crowd unless you’re leaving early- that said crowd management is very good

Yes

There are three - Hyde Park Corner (south), Marble Arch, and Lancaster Gate (north).

Unless you want to be at the front then early, but you don’t seem like you want to do that. Bearing in mind it’s also on big screen, then a hour before would be ok. There’s lots of mobile toilets, if you can put up with the smell. Plus no drinks are aloud in to the arena & are confiscated on the way in. Hope that helps.

Being that Hyde Park is such a huge outdoor venue, I would expect that you would be able to take a picnic blanket, like most outdoor events. It's best to contact the organisers of the event itself just to confirm this. I've been to Proms in the Park, at Hyde Park, and picnic blankets were more than welcome.

Hi, yes that should be fine, it’s also on in st James park & green park. Hope that helps.

Hi, one is the closest, then two & your right tier 3 at the back. But there’s large screens so you don’t miss anything. Plus the less tickets are sold the near you will be. And they won’t let anyone in with soft or hard drinks. They charge £5 for a bottle of water, which is nice of them, lots of people sit out of the concert area & can still see the screens & have a drink soft or hard. So stop worrying & have a great time on the day & take no drink. Hope that helps.

Unfortunately they are the last act on & it’s normally a hour. Lots of people sit outside of the concert area, then they can have a drink & listen to the concert for free & leave before the crowds start leaving in drones. Hope that helps.

Kann ich leider nicht beantworten.

It depends on how near the front you want to be, earlier near the front, or later at the back, but it’s on huge screens as well. And don’t take any drink with you, as they will take it off you before you enter, then they charge a lot for a bottle of warm water. Hope that helps.
