My husband will be at a conference in London in November and his boss has said he can upgrade to a family room to allow us to take the kids and have a day out down there. It would be in term time so would take our 4 year old out of reception, and also would have our nearly 3 year old with us.
We will aim to get there for early afternoon on the first day and have the rest of that day and evening together, then I would have a full day with the kids while DH is working. We will be staying in the Westminster area.
So any suggestions for what to do / see? We don't have a big budget but would like to make the most of the time there. DS1 is dinosaur obsessed so the natural history museum is probably on our list. Other than that I'd really appreciate a few ideas.
