Double pram or toddler seat??

[Feijoa Mum]

I have been having a bit of a look at what is available and I am stumped. I would love to get a toddler seat for my pram, Valco Everest but they dont seem to do one for that style.
I have a girlfriend who has twins and she originally started with a side by side pram but then swapped to the back and front type (Sorry I hope you know what I mean, my explanation is a bit vague.) as she didnt like the the restrictions the side by side had.

Scout will be almost 2 by the time this one arrives so do I even need a double pram?? I had a toddler seat on a mountain buggy with my first two boys as they were 19mths apart and it was well used which makes me think I would prefer to have the option than not, but I just dont know which way to go.

Any opinions greatly appreciated.

I have the adventure buggy, toddler seat alot easier I think just trying to manouvere around shops can be hard enough with a pram let alone a side by side.
