This article talks about the impact of the supply and demand law on the hotel rates.
One can see that at the end of 2009, the economic crisis is not over as the hotel rates have decreased between 5 and 15 % compared to December last year. Hotels are now making efforts to adjust their rates so as to still attract customers. In United Kingdom, prices have been decreased (in Edinburgh by 15%, in Birmingham by 19% etc...) even if this country remains the top country of high hotel rates.
However area of growths for hotel rates are still found with special monthly events in cities offering Christmas markets or cities organizing unique events like Copenhagen for the World Climate Conference (hotels increasing their rates up to 21%). In these cases, they are never enough hotels in the cities to cater for the demand from visitors from all over the world.
