It has been around for ages. One company I work for has specific agreed rates at certain hotels and at other IHG properties has an across the board 20% discount off of the flexible rate.

For 2014, it is all down to what your company has negotiated with IHG for the year. The generic 20% discount on all hotels where no specific negotiated rate exists, works well for me. What one company negotiates does not mean that there is a generic change to corporate rates
