when will we get to know all the activities the royal family will carry out during games time?
The Monarch website has a 'Furthcoming Engagements' page although that may only be updated a day or so beforehand.
At the moment it has the following engagement listed
15th July -
Princess Alexandra
will attend a Service to mark the Olympic Games at Westminster Abbey, London, SW1.
16th July -

President, Creative Youth, will attend a performance of 'The Dreaming' at the Rose Theatre, 24-26 High Street, Kingston-upon-Thames, Surrey.
The Countess of Wessex
will hold a Charities Forum at Bagshot, Surrey.
The Countess of Wessex
will open the newly rennovated Lightwater Surgery, 39 All Saints Road, Lightwater, Surrey.
The Princess Royal
President, British Olympic Association, will attend a Reception with 1948 Olympians at Team GB House, Westfield, Stratford, London E20.

Patron, The Boston Stump Restoration and Development Appeal, will open new Community and Visitor Facilities at St Botolphs Church, Wormgate, Boston, Lincolnshire.
The Duke of Gloucester
will open the new Olympic Wing at St John's Church of England School, Buckhurst Hill, Essex.
It does continue past this but this is just for the next couple of days.
However there are often times when something makes it into the CC that isn't on this list and of course, if something happens e.g. an illness, something planned may not take place such as a couple of canceled engagements earlier this year when Philip was taken ill.

If you search to the end of the month it is announced that The Queen and Philip and Anne will attend the Opening Ceremony - with The Queen Opening the Games of course. The Duke and Duchess of Gloucester and The Duke of Kent are also listed as attending the opening ceremony. No other royals are listed as attending the opening - but that is because they won't be there officially.
Over later days it has Anne attending the games and the Duchess of Glocuester attending the tennis with the Duke and Duchess of Gloucester also listed as attending the Canoe Slalom.
