It may be kitschy and pricey, but Madame Tussauds makes for a fun-filled day. There are photo ops with your dream celebrity (be it Daniel Craig, Lady Gaga, Benedict Cumberbatch, Audrey Hepburn or the Beckhams), the Bollywood gathering (sparring studs Hrithik Roshan and Salman Khan) and the Royal Appointment (the Queen, Harry and Meghan, William and Kate). Book online for much cheaper rates and check the website for seasonal opening hours.
If you’re into politics, get up close and personal with Donald Trump who stands uncomfortably close to Vladimir Putin, while Luke Skywalker and Han Solo enthusiasts can turn to the Star Wars experience, which features a host of its key heroes and villains in iconic settings.
The whole place is pretty commercial, with shops and spending opportunities in every one of the dozen rooms. But the Spirit of London taxi ride through the city's history is great, educational fun, and the new Search for Sherlock Holmes (£5 extra) is theatrical.
The museum has a long and interesting history, which started when the French artist and model-maker Marie Tussaud (1761–1850) made death masks of people guillotined during the French Revolution. She came to London in 1803 and exhibited around 30 wax models in nearby Baker St, providing visitors with their only glimpse of the famous and infamous before photography became widespread.
