A must do in London. Buy tickets online plus one attraction (Madame Tussaud s) which helps you save some time and money and you can select the day and time you want to visit. I noticed the price is higher if you are visiting the same day, I would suggest to plan in advance. When you get there, the line looks insane, however, it runs pretty fast.
Tip: you can also view the London from top at the Shard , you can choose one during day time and one during evening after dark. It closes at 8:30 pm, we went at 8:20 and it was a great evening view.
