The Lanesborough St. Regis, a luxury hotel which is adjacent to Buckingham Palace, is inviting world travelers to join them in celebrating Queen Elizabeth II’s milestone with the Diamond Jubilee Package. The special promotion takes place the weekend of June 2-5, 2012. It includes four-nights in an executive-double room. Visitors will attend the prestigious Epsom Derby on Saturday, June 2, while taking in the comforts of the Derby Suite throughout the day at the races. The following day will present an opportunity to view the Thames River Pageant, as it reaches the Tower Bridge, aboard the HMS Belfast. This flotilla, which is a 7.5-mile procession led by the Queen’s Royal Barge, includes up to 1,000 boats, ships, and steamers from around the world. A five-course Michelin-starred dinner will be served up at the Lanesborough’s Apsleys restaurant the following day. On the last day, June 5, guests will be able to view the Royal Carriage Procession to St. Paul’s Cathedral from an exclusive vantage point on the Strand. The package is available for £5,400; rates are based on double occupancy.
