Hey Tomk81 - that's exactly what I did. She checked last night in all 3 cabins:
WT: £1,008.90 (price for both of us)
WT+: £1,780.90
CW: £5,436.90
CW feels a little on the heavy side for me, but I think WT+ might be a reasonable option, and then I can cross my fingers for the PUG to CW (at a reasonable price, of course).
