I needed to stay in London at short notice last week - a room was available and the price was half what I could have got at a hotel through something like Last Minute.com (having read this thread I had a look to make a comparison). This pretty much saved my annual membership fee. I've always found the Club very helpful and if Mrs Approach needs to stay in Town she feels happier there than in a hotel.
If I looked for a criticism the Running Horse and bar meals could be available later into the evening
