LONDON, Nov. 18, 2016 /PRNewswire/ -- Many vacationers and business travelers are unaware that a hotel reservation can be sold if their itinerary unexpectedly changes - RoomRoomBooking ( http://roomroombooking.com/) is a new marketplace for doing exactly that. "If for any reason you can't use your hotel reservation, why not sell it to someone who can?" asks RoomRoomBooking Founder Pedro Bastian. "With this innovative model, everyone wins. Buyers get great rooms on short notice, sellers aren't stuck with a reservation, and hotels don't miss out on revenue." RoomRoomBooking has been designed with ease of use as a top priority for both buyers and sellers. Prospective sellers should first contact their hotel to ensure that a reservation is indeed transferrable and to pay any associated fees. Next, sellers create a profile on RoomRoomBooking and fill in the required details of their reservation. Buyers can then browse or search the marketplace to find their ideal room. The marketplace handles payments made with most major cards and PayPal. Sellers receive their payments via PayPal (minus a 10% fee) on the first day after the buyer checks out of the room. RoomRoomBooking has already earned the praise of travelers who have booked rooms on in cities around the world. "I made the payment for the reservation with PayPal, and I could rest assured that everything would go smoothly," says one satisfied user. "In the event my plans changed or something went wrong with the arrangements, PayPal offers you the option to terminate the transaction. RoomRoomBooking also gave me protection as a buyer. But, everything went fine. The reservation was in my name and it was already paid when I arrived." Trust and reliability are paramount concerns at RoomRoomBooking. That's why sellers get paid after check-out, not before; this prevents the same reservation from being sold to more than one buyer. In addition, the site takes every measure to protect users' identities and prevent fraud.
