You can now create your own InterContinental Hotels Group edirectory, but unfortunately it only includes hotels in Asia, Middle East, and Africa.
You can search for individual hotels or certain brand etc. This can come very handy at times when you need more information about a specific hotel.
Here’s the info about InterContinental hotel in Phnom Penh, where I am going to stay again later today.
If you have trouble with distinguishing between different IHG brands, the directory also has a brief introduction of each one of them.
It also lists the number of IHG properties by brand and then in the Asia, Middle East, and Africa region as of December 2011. Still more than two thirds of IHG hotels are Holiday Inn and Holiday Inn Express ones.
