Here's a date for your diary. Between 23 July and 30 September it is possible to book a tour of the State Rooms and Garden highlights at Buckingham Palace. You will need to leave about 3 - 3.5 hours to enjoy the whole experience. You take the State Room tour first and, to mark the Prince of Wales' 70th birthday this year, there is a special display entitled 'Prince and Patron'. After the State Rooms tour, you will have the chance to grab a few refreshments before joining the 45 minute garden tour. For the horticulturalists among you, this is a must! The cost is £33 for an adult and U17s are £19.70; U5s go free. To find out more visit the www.royalcollection.org.uk website.
