Room X-Ray

Rent a car for your trip — compare deals, free cancellation

Room X-Ray helps you X-ray hotel and Airbnb reviews. When you're ready to book, you often still need a car — airport pickup, coastal drives, or neighborhoods far from transit. We partner with Discover Cars so you can compare 1,000+ rental brands with clear pricing and free cancellation on most deals.

From the Chrome extension — city and dates included

After a review summary loads on Booking.com or Airbnb, tap Compare rental cars in the panel. We send your destination city and stay dates (when the listing URL includes them) so Discover Cars can pre-fill pickup and drop-off — less typing, faster search.

Car rental FAQ

Why compare rental cars after reading hotel reviews?

Once you know the property is worth booking, the next friction is getting around — airport transfers, day trips, or remote neighborhoods. Comparing rentals in the same city saves time and often money versus last-minute counter rates.

Does Room X-Ray book the car for me?

No. Room X-Ray only links you to Discover Cars, a comparison site with 1,000+ rental partners. You complete the booking on their site at the same transparent price they show.

How does the extension pre-fill my rental search?

When you open a Booking.com or Airbnb listing with dates in the URL, the Room X-Ray panel passes the city and stay dates to our redirect, which forwards them to Discover Cars so pickup and drop-off are closer to your trip.

Is this an extra cost on top of the hotel?

Car rental is separate from your accommodation. Room X-Ray earns a commission if you book through our partner link — it does not change the price you pay on Discover Cars.
