so tomorrow I am being good mummy and good DIL and taking dd (4.9) and ds (2.9) on the train to London to visit my Step Mil for lunch (DD is refuting my assertation that they really will make an onion into a volcano for her at Benihanas). Afterwards (so about 2pm) we were going to go up to the museums for a couple of hours. Am I mad? Will the queues be horrendous? I haven't been for years, and then it was without kids. So what are the best bits to do for a smash and grab visit? I've promised them dinosaurs, so we will have to go to NH, is it worth trying to go to the Science Museum basement as well?
Thank you very much for any suggestions
