I really HATE the wording some Hyatts use on the cancellation notes, especially when booking on points.
I just made a reservation where the wording is:
Cancellation Policy
One Night Deposit. Full Charge Cancel 60days Prior Arrival
Then, in the email I have:
CANCELLATION POLICY: 1NT DEP DUE AT BOOKING. FULL CHARGE IF CXL 60DAYS PRIOR ARRIVAL
I've come to generally believe this to mean that if I cancel more than 60 days before the reservation, there is a full refund of my points and deposit. But it's really not at all clear.
I don't even know where the implied punctuation should be. In the first example, you could put "unless" in between charge and cancel. But in the second one, there's an "if" that makes no sense whatsoever.
This is one example, but I see it all the time.
Contrast this type of wording with a different type I sometimes get:
CANCELLATION POLICY: 48HRS PRIOR TO CHECK IN TO AVOID 1NT FEE
To me, 100% clear. Using this wording, the previous hotel could say CANCELLATION POLICY: 60DAYS PRIOR TO CHECK IN TO AVOID FULL STAY FEE
