Greenwich
When researching London my husband came across Greenwich. The opportunity to straddle the Prime Meridian was just too good to pass up. Also, it was such a fun day trip and part of London to explore. The fastest and most fun way to get there was to take a boat down the river. The kids found this fun and it was nice to get a different vantage point to see the city. We highly recommend visiting if you are ever in the area.
