There are lots of things to consider when you're planning a hangout, but cost and accessibility will always be high on the list. This is one of the reasons why London's parks are great locations for all types of events. Free, and on main public transport routes, they're a convenient and cheap place to meet.
London's park's provide ideal hangout locations for nature lovers, sporty types and groups that love history, art and architecture. There will be plenty of space, plenty of opportunity and more often than not, somewhere to eat.
So, have a think about choosing one of these London parks for your next hangout.
Holland Park is probably best loved for its sense of tranquillity, which means it's a great hangout for groups trying to forget they're in the city.
The beautiful Kyoto Garden is one of the west London park's main attractions, but for people who want a more lively meet the sports facilities include football pitches, tennis courts, netball courts, golf practice nets and cricket practice nets.
The park also appeals to environmentalists, thanks to its thriving woodland and Ecology Centre. There's a restaurant, cafeteria, orangery and hostel on site, too.
The most famous gardens in the world make for a fantastic hangout because nature, history and art can all be found within the luscious Richmond grounds.
You could take a group stroll around the gardens, and above them on the treetop walkway. Or maybe just sit and chat by the lake or water lily ponds. Groups with more exotic tastes can try The Prince of Wales Conservatory and the Palm House. There's also the Georgian splendour of Kew Palace to admire, the secrets of the Royal kitchens to discover and art galleries to visit.
Alternatively, you can just enjoy the scenery while you have a leisurely lunch in one of the garden's cafes or restaurants.
With beautiful views overlooking the city, ancient woodland and expansive open grassland, Hampstead Heath is one of the most popular green spaces in London.
It's often associated with romantic walks, but it's also an ideal hangout spot for sporty groups, or people who just want to be a bit more active - even if that just involves flying a kite.
The public facilities include a lido, swimming ponds, splash pools, football pitches, cricket pitches and an athletics track. Or, you can easily come up with your own way to make the most out of a meet at Hampstead Heath.
Richmond Park may be the largest of all of the royal parks, but it's also one of the most peaceful - so peaceful, in fact, that deer roam freely through the grounds.
There are also a wealth of activities that would make for an enjoyable hangout. They include cycling, horse riding, two golf courses and fishing at Pen Ponds. For those who want a more relaxed meet, there's the option of a wander around the organic woodland garden.
You can also get together for a meal at Pembroke Lodge, a gorgeous Georgian mansion with fabulous views and outdoor seating. Or if you'd prefer a more casual lunch, try Roehampton Cafe.
Bushy Park, which is just to the north of Hampton Court Palace, is a brilliant hangout for nature lovers. Aside from free roaming deer, it boasts a diverse array of animals, birds, waterfowl, plant and fungi.
It's also a good place for groups that want an active meet because cyclists are welcome on parkland's roads, and horses can be ridden on rough grass areas. If you've worked up an appetite during the hangout, The Pheasant Cafe offers hot and cold snacks until dusk.
