The link I have been circulating is now not working, apparently, because there is a maximum number of bookings that can be made per employee and that link has hit its target.
I have a replacement link (same rates as befpre, still non-refundable, still theoretically no points) so please drop me a PM if you want it. I think you'll also need this if I sent you the previous one but you've not yet booked. Replies will only come during UK daytime!
