When we finally found a week that would work for all four of us to visit London, we had no idea that we would overlap with the Queen's Jubilee! My mother was excited when she realized we could watch the 1000 boat flotilla on the Thames. We ended up having the same view of the flotilla as my mother did in Canada --- from the television in the apartment we rented since the thousands of people that lined the banks of the river made it impossible to see anything, plus it was raining, no surprise!
