I would recommend anyone visiting London should go to Greenwich and see the observatory.

Wonderful insight into the origin of longitude using time and its importance to shipping. Flamsteed House is beautiful and gives a real feel of the life of the Astronomer Royal and his family.

Not bad at all. The place has a lot of history and you have a lot to learn, plus you will get a nice selfie on your facebook page 😎.
The view of London from the top of the hill is great, the park around is nice and the restaurant is good.
Staff is pretty much useless but they are willing to help and will try their best.
All in all you will have a full day.
Enjoy 😉
