Have any of you done the London Walks "Historic Greenwich" tour? I'm wondering if £3 for the boat ride is roundtrip or just one way? Also, is the tour only 2 hours (as their other tours are)? That doesn't seem like a lot of time and I'm wondering if you actually tour any of the sights (such as the Old Royal Observatory) or it is more just a glimpse from the outside? Lastly, would you recommend this as a good way to see Greenwich? Thanks in advance!
**And yes, I have visited the walks.com website...my questions were not answered there and I was hoping to hear from someone who has actually done the tour.
