The afternoons as we approach our last admission time tend to be the quietest time of day, however please note that this can vary a lot depending on the day and is never guaranteed.
While we would advise that, although it is difficult to predict what the attendance will look like on any specific day, school holidays and weekends tend to be our busiest days.
We do offer Quiet Sessions on selected dates, where we have adjusted our opening hours, with limited tickets available, to provide a quieter Madame Tussauds London experience that aims to provide a more comfortable visit for those with autism and other sensory requirements.
