Thoughts? I live in greater London and occasionally use the tube and until now I've never been near an escalator with the buggy. Always gone routes though stations with lifts. But now I am just exhausted with spending hours going really long routes and I see people going on the escalator with their buggies and seem perfectly fine! I have a baby jogger city elite and gt, but feeling I probably need an umbrella type if I'm gonna attempt this one... Oh and LO is 18months...
