I'm not all that familiar with London aside from superficial site seeing. I'm taking a friend - who has been like a second Mum since mine passed away - to London for their first time in November. I have days planned (major sites, Thames Clipper, afternoon tea) but am panicking about one bit of travel. How on a Sunday evening would you get from the London Eye to Vauxhall Travelodge? Her mobility is okay but not great, we'll only have one debit card so I think that rules out buses. Will there just be a taxi I can hail? Sorry for the obvious question, I think it is the sense of obligation to one of the world's loveliest ladies means I am over thinking it. Thanks in advance.
