I think it's going to be more bother than it's worth to me. I go away for pleasure and potentially turning that course even this much is something I can forgo. If it was as simple as ticking a box on the website as I booked then yes, I'd do it. But I'm not the type to go loaded with the T&Cs on hand just in case the receptionist doesn't understand or, go down for breakfast and get stopped and have to explain it all again. I've just made 180,000 avios for £117 so will let this one slide.

Thanks everyone.
