Is there a cancellation fee for some hotels; can you note if there is or there is refund due to cancellation

The cancellation policy is in the confirmation email we send as well as on the offer details page, located under the MY TRIPS —> MY RESULTS menu.
We never offer hotels that are non-cancellable, non-refundable or pre-pay. We also automatically stop searching if we reach the “Cancel By” date of the currently booked hotel (if any). So you should be pretty safe from this perspective, but always review the Cancellation Policy on the “MY RESULTS” record for the booking in question just to be sure.
So sorry for the late reply, this was a support question submitted as an idea and just tonight we found a handful of those that we missed from a while ago.
