Can anyone recommend suitable activities to do in London when 7 months pregnant? We will be staying near Tower Bridge in June for 3 days & want to make the most of our last 'child-free' break, without it being too hectic. I particularly fancy doing a ghost tour, but was a bit concerned that it may not be suitable, as the walking may be too much, can anyone advise? I looked into the ghost bus tour as an alternative, but this seems to be more comedy than scary! I would also like to do a river cruise & perhaps visit a market. I would appreciate any advice on a suitable 3-day itinery?
