I signed up for Voyage-Prive today (Voyage-Prive.co.uk) and they were offering the IC on Park Lane in London for £115 a night. As note above, this includes tax, b'fast and an upgrade to a superior room.

Availability was lousy for Tuesday or Wednesday but otherwise quite good.

You don't need a referral for VP but if you do want to PM me for one I'll get a £10 credit if you go and make a booking.

It'll be non-ref and presumably no points awarded but the price looked quite keen to me.
