Many hoteliers were expecting a bumper month in April due to the marriage of Prince William and Kate Middleton.
However, the latest figures reveal a dip in performance for hotels in the capital.
According to April's HotStats survey of four and five-star chain hotels, the royal wedding did not have a positive effect on London hotel market revenue and profit performance.
Jonathan Langston, managing director of TRI Hospitality Consulting, said: “Data from our HotStats survey indicates that over the bank holiday period of the Easter royal wedding and May Day, London market performance dipped.”
Compared to April 2010 Total Revenue per Available Room (TRevPAR) in London grew 11.2% in April 2011 to €173.83.
Profits (measured as the total gross operating profit for April, divided by the total available rooms during the month) increased 13.3% to €76.14.
In March, both figures were higher: TrevPAR was €182.59, while profits stood at €87.19.
The strong growth in April was due to the “rebound effect” from the Icelandic ash cloud, said Langston, which “severely affected” London performance last year.
