The Times published their research and found the Savoy, The Dorchester, Park Plaza Westminster Bridge, Marriot Grosvenor Square and One Aldwych are all sold out. Even all of the 12 Radisson Hotels in London are sold out and out of the 22 London Hiltons all they have left on offer is a room at the Heathrow branch.
Is there any room at any of the inns? The good news is there is but it’s going to cost you---a lot. We managed to find rooms at the Langham London with room rates from £539 a night for a classic room (usually £269), Swissotel The Howard with online rates from £335 for an Advance Saver Premier Room (usually £155), The Chesterfield Mayfair with room rates from £375 for a classic double (usually £180) and Threadneedles Hotel charging £382 for a luxury room (usually £180).
Even a room at the budget Tune Westminster will cost you £140 (only £65 for a room two weeks earlier). And all of The Holiday Inn and Premier Inn central London hotels are sold out. So you if planning a trip to London for the Royal (Rip Off) Wedding you had better be fast and have cash.
