I dont know how to rate this tour as we didn't get to see it. We saw the Cuttysark and is quite marvelous, but we couldn't get to the mean line nor the Observatory. We had no idea how far it was from the dock nor that it was all uphill! We didn't see a bus or taxi and just couldn't make the climb, bad knees and seniors. So unless you know this ahead of time, which you're not told, its a long climb. We'll try next time we go and get a taxi.

Travelled to the observatory by train and was easy enough to find. My trip was in Winter and while the Gardens were very picturesque, they would be incredible in Spring, Summer or Autumn. I did not know the Queens Hoyse and Gardens existed.
The Observatory exhibition was excellent - fascinating - and worth going to. I didn't go into the Planetarium, but now wished I had. A combined reduced admission fee for both would have been encouraging!

Perhaps not for everybody but standing on the Primer Meridian and the accompanying museum regarding time and clocks, etc, was great fun. If you just want to stand on the Prime Meridian cool but the museum was chock-full of information, history, and was a very interesting learning experience.
