If a hotel has rooms available and are unlikely to fill them, they release the extra capacity to travel sites.

As the hotel doesn’t usually offer these rates to the public they market them as “undercover” or “top secret” hotels.

Only a few criteria are mentioned such as the general location, star rating and description.
There are a few tips you can use to try to figure out what hotel you are booking such as the hotels location and reviews if you have a specific hotel in mind.

In most cases if you are willing to pay upfront before you know the hotel you are staying at, choosing an undercover hotel can get you a 5 star room at 3 star prices. Up to 90% of people that select an undercover hotel would do so again based on their experience.

Undercover hotels aren’t restricted to a location or star rating. You can get luxury undercover hotels, cheap hotels and even save some money by searching for top secret hotels at airport locations.
