Vouchers for Windsor Castle

Here's a list of Kellogg's products with the voucher. Ensure you take the voucher with you on the day. It can only be used against the gate price, not the discounted online price. The age classification for an adult ticket varies between attractions so make sure you check before you go. Valid for standard entry tickets only.

Also check the venue's individual opening dates as some are closed at certain times of the year. For example, Chessington, Legoland Windsor, Alton Towers and Thorpe Park close in November. There are also some extra excluded dates listed below:

• Every Fri and Mon until Sun 27 Mar, and 29-31 Oct 2016 at The Blackpool Tower Dungeon

York Dungeon is currently closed due to flooding in late 2015 and there isn't a timescale for when it will reopen.

Promotional vouchers don’t guarantee entry into attractions in the event of venue capacity being reached. Offer can't be used with any other offer or concession, reward or loyalty schemes, pre-purchased/advance tickets, online or call centre bookings, combination tickets, two day passes, annual passes, Q-bot, Fastrack, priority entrance, early ride time, secondary ticketed events, hotel events or group bookings.

Or book online in advance using promo codes on cereal packets

To guarantee entry in advance, you can book tickets online (excludes The Blackpool Tower Circus) at a special Merlin website ahead of your visit. To do this, you need a unique 10 digit code found on promotional packs of Kellogg’s cereal only, either underneath the carton flap or on the base of the box.

This method of redeeming the offer requires you to pay the gate price in advance and print out your tickets. At selected attractions, you can scan these tickets and walk right through the gates, enabling you to beat the queues.
