RoomsNinja lowers the price of hotel reservations for travelers after rooms are booked. RoomsNinja assesses more than 25 global vendors, providing an inventory of more than 400,000 hotels worldwide, with multiple offers per hotel. Once it finds the traveler's exact reservation at a lower price, the service rebooks the new, cheaper reservation and cancels the old one, taking into account all the different parameters and cancellation costs/policies. RoomsNinja was developed by MST Travel Ltd.
