A quick update.
Stayed here for 2 nights this month.
We had a view of the mountains on the Regency Club floor. Didn't ask for any upgrade as space wasn't important and we enjoyed the balcony briefly.

The Regency Club was closed but we were given the extra points at check in and had breakfast in the Corn Maiden which was very good.

At check out the charges hadn't been removed from the bill so the desk clerk removed them but left the gratuity. Usually I let this go but having to ask to have the breakfast charges removed made me cranky I had to pull up the diamond benefits on my phone to show the clerk as he had never heard of this benefit....

Otherwise a very good stay. The pool was heated to 83F so it was warm enough to enjoy even in February and one day it was actually 70F+
Had free access to the spa and had the whirlpool to myself for an hour but it was lightly snowing at the time (I hadn't realised it was an outdoor whirlpool). It was very relaxing provided I kept my shoulders submerged.
