Every tourist should spend an hour riding the London Eye at the start of their break, as it gives a great overview of the city.
I have been on it in the past and it is one way of seeing the capital from a different view, night or day. The London Eye was created I think originally in 1999 to mark the millennium, the year 2000.
Which one would you recommend.. Day London eye or Night London eye?
Is it worth to do a river cruise after London eye?
I am planning to have a evening/night London eye + river cruise.. any cruise recommendation?
I'd probably recommend... them both. It's hard to choose. They're both good, and you should enjoy either one. But the view will be better during the day. Night views are impressive, but I always think it's very hard to pick out individual landmarks because the lights all look the same. You'll be able to see the easy ones, like the dome of St. Paul's, the Houses of Parliament, and big skyscrapers like the gherkin and shard, but distant parts of the city will just be indistinguishable office lights. ...but it will still be good. It's still worth doing.
