The Club is a great asset to have in central London providing good, cheap accomodation. I use it from time to time, generally at short notice. Sometimes I can get a room, other times it's fully booked but then I frequently find the same thing with hotels all over the country.
A few years ago my wife was quite seriously ill and transferred to St Thomas's hospital from Norfolk where we lived. We had three small children at the time. I have to say that the Club was extremely helpful over weekend visits to see her, arranging a room, putting extra beds in and generally helping where they could.
The only downside to the club is that, having regard to one's spouses automatic membership, it's a bit close to the shops and the front desk are far too helpful at storing shopping bags.
