It is Kids Week, meaning that from 12 August to 4 September a child aged between five and 16 can see West End shows for free when accompanied by a full-paying adult. Up to two additional children can also get half price tickets in the same transaction.
There are 31 shows to choose from including Shrek and The Wizard of Oz. You can book from now up until 4 September via the Kids Week website or by calling 0844 248 5151, although tickets are subject to availability and you can only book up to eight tickets per booking. Kids Week ticket-holders can also attend some show-related activities for free. But remember, you need to buy a full-price adult ticket to take a child for free and there may be promotions elsewhere on these, saving you more than getting a free child's ticket. So check this first.
