I travel 2-3 days a week for business. When you book an online reservation at Hilton, it gives you Cancellation Information - which is often very important to know - but I am concerned they are deliberately vague. The online cancellation information says "Cancel 2 days in advance" or "Cancel 48 hours in advance." After you make the reservation you will eventually get a confirmation email, sometimes delayed or sometimes going to spam. The confirmation email says, way at the bottom, 6-8 screens down, "Cancel 48 hours in advance by 4 pm." Obviously, the website and the email should say the same thing. If the rule is 48 hours AND 4 pm, then just say that on the webpage during the reservation, don't hide the secret-secret cancellation time til later when it is unlikely to be seen. I got caught calling after 4 pm (a time I hadn't been told about) and was told that people complain about this all the time. That really annoyed me. It suggests the hidden information and ambiguous information is, really, deliberate.
