Well looks like Germany will be losing three InterContinental Hotels on April 1 2011. This statement can be found on each of the hotels pages, "THIS HOTEL WILL NO LONGER BE AN INTERCONTINENTAL FROM 1ST APRIL 2011"
So time to say goodbye to the InterContinental hotels in Berlin, Cologne & Dusseldorf. I'm told from someone familiar with the matter, that IHG just said, "We are done" and told these hotels that they will no longer be a part of the brand.
The InterContinental in Frankfurt, Hamburg and Berchtesgaden are not effected.
