I have to come into London (from north of London) next week for a childrens' party and am petrified! I've never travelled on public transport with a pushchair, let alone in London.
Getting in should be OK (coming in at lunchtime, so I guess trains will be relatively quiet). But we'll be coming back somewhere between 5 and 7 (depending on how tired and grumpy the dcs are). Is it really going to be feasible to get on and off a train with a double pushchair at that time of day?
