Lovely stay, great food and pleasant spa. Very embarrassing situation on arrival when the staff would not accept Northern Irish Bank notes as payment. They insisted on contacting their accounts department which wouldn't answer. I was told "it's important to be thorough" by a supervisor hiding in the back room, when I pointed out they are legal tender anywhere in the UK. Luckily enough, common sense prevailed when a shift change happened many hours later, and a very polite man verified the notes would be absolutely fine as they are Stirling and no different to a Bank of England or Scotland notes.
