MUST be a mistake, it's too low? Now what happens if I jump on it and book it, payment is taken at once from my credit card. Can they refuse to honour my booking? It's a 5 star hotel part of one of the major luxury hotel groups.

It's in North America and I'm in Ireland so it would mean buying my air ticket soon also.....could the website turn around and say we've made an error and refund my money back to my card (which would be no good because I'd have my flights paid for!) Or are they bound to simply honour it? Thanks
It's for a 2 week stay and from my calculations because of their error I'll save about $1,500! Happy days!......or not maybe?
