When we were planning our trip to London, we wanted to make sure to see everything we wanted properly. For example, we decided not only see London Eye but also buy tickets to actually ride it.
It was a bit hectic around London Eye, a lot of tourists but waiting in line for tickets didn't take as long as we thought it would. We were very lucky with the weather and it was a very nice day with the sun shining!
It was very cool watching the city from the top of London Eye. Seeinng the city from up there, made it even more clear that London is a much bigger city than you realize.
