Prior to becoming parents, my wife really wanted to visit London and Paris (and mainly do the tourism stuff) - mostly in London. To make a long story short, we never got around to it, so I owe her this trip! We are likely going to do the trip in 1-2 years, once our daughter is 6 years old.

A few questions:

1. Other than the typical tourist attractions, anything else you would recommend seeing/experiencing?

2. Any recommendations for a 6 year old? Other than Paris Disneyland!

3. How long does it take to go from London to Paris via the Chunnel? Is it a simple trip, no transfers?

Thanks!
