Posting for traffic- thinking about taking 15month DD to London on the train (2 1/2 hours ish) for the first time to see friends but we live rurally and so have an uppababy vista which is great but not small. Would it be completely impractical to take her in this? I'd prefer to take ours as I know how it works, she likes it, roomy basket and she's up high, but I'd be on my own to navigate tube/buses.
Would I be better to try and borrow an umbrella stroller? Or am I just worrying over nothing?
