Many secret hotel deals are flash sales, which expire quickly. It is possible that when you click on the Reveal Hotel link, the deal has expired. Please refresh the hotel search result by clicking on the Search Hotel button and then try again.
Occasionally we have a difficulty to find a good match because different vendors have different prices and feature descriptions on the same hotel. In that case, you can do a manual match with FindOptimal. Basically you may use the filters or controls other than price to narrow down the result list to match the characters of the secret hotel and see which regular hotel is left in the final result set.
