The agency will produce a drinks reception to follow its unveiling of a present from the Queen and Prince Philip at the Queen's Cup event on 12 June. Smyle will then host an Argentinian barbecue for 500 players and grooms.
On 24 July Smyle will also manage the Official Player's Marquee following the Cartier International Polo match. The event will take place in a Tentology-manufactured structure from Canada.
Smyle director Rick Stainton said: "We will be delivering a unique set of events."
