If I use my points I only use them for rooms I'm prepared to stay in not just to use them up.

If I use my points at the CP LHR T4 then that's the standard room which meets my needs and would pay cash for it. I'm only there over night so it's fine for me.

At the Kimpton de Witt it's a (King) Essential Room. If the only points room is available is a 'double city single' then I'm paying cash for a larger room

I did buy points in the recent sale but only after double checking the calculations of the cost of buying the points vs the cost of a cash booking. For the bookings I was looking at it was cheaper to buy the points than pay for the stay 250k points for £ 960. Cash cost BFR £ 1,300.

One thing I do find is when a lot of people buy points - whether its for hotels or airlines - they have little or no real appreciation of their value and so then get angry when they don't get the value out of them. It was the double points offer that I opted for as a 60 or 80% bonus doesn't cut it for me
