Also, I did some inside studying.

Everything but Trip Protection is refunded.

For purposes of the Sunshine Guarantee, daily rainfall is measured at your destination airport and not at your hotel or other location. (I wonder what "purposes" they're talking about?)

The daily amount of rain that falls at your destination airport will be determined from measurements provided by the National Weather Service or other independent agency. Rainfall will also be audited by a private independent provider of weather information. Priceline will use the data provided by these agencies to determine if a refund applies. (A "private" provider of weather info? If that's not deceptive, what is?"

Other than that, I don't really see anything else that is too suspicious. Although, I don't like the fact that you have to wait 21 days to get a check in the mail "IF" you do qualify for a refund.
