I may be missing something, buy I was under the impression that the OP was upset over the whole lack of Customer Service and the poor excuse for breakfast was just the straw that broke the camels back. The breakfast coupons are within the ‘letter of the law’ of the minimum definition of Continental Breakfast.
With regards to BC Park Hyatt, I’ve stayed there several times, and I agree when it comes to service it is a very poor excuse for a Park Hyatt. The only reason I go back is I really enjoy skiing, and it is the only true ski resort Hyatt has. When I am there I often get the feeling the staff thinks they are doing me a favor by letting me be there. They always seem to screw up the bill, take 5 hours to deliver the Diamond amenity, not manage to get the room cleaned etc.
It should not be a Park Hyatt.
