Vending Machine location

When 4-5 friends come to buy snacks together, how would their movement around the V.M look like?

1) it seems to be more active and fun when you can walk around the V.M in circle with your friends.
2) in the corner seems to be boring and passive. not exciting.
3) each V.M at different places(floors) seems to be difficult for 4-5 people to buy snacks together.
4) V.Ms in a room feel stuffy, closed.
5)'U' shape room gives better space, more active, interactive than #4.
7) V.Ms located separately in a room seems to be meaningless, they should be united in order to fit into my concept.

So I liked the idea of walking around the vending machines in an open space. I think every cultural vending machine should be located at the same place for convenience and for the united feeling.
