Go for it Skye. While I will not say that you cannot take a trip to London, or anywhere for that matter, with children, it is definitely a different type of experience to have them along and the cost is obviously much higher with the added travelers.

I took my daughter with me on a trip to Japan when she was five years old. She still remembers parts of it and I would not have denied her the experience for anything. And as I type, I am planning another trip there for next summer when she will be only ten.
