We’re an older group & walking is at least a little difficult for one or two of us. But your walk sounds nice. I’ve been looking at a hop-on, hop-off river cruise that starts at the Westminster bridge & goes down to Greenwich. We’ll be in London for three full days. I’ll add your suggestion to my notes. Thanks! :-)
hmm... a hop-on, hop-off is good. Let me know (if you wish) where you plan on staying and roughly what you’d like to see and I can give you suggestions about good restaurants, sights etc. — you may send a private message if you wish. Have fun - London is a lovely city
