If you want to yield your prices a lot or if you are already doing that, an RMS can make it easier for you. An RMS is there to help you optimise your room sales. Ask yourself if the extra revenue will outweigh the price you pay for an RMS. For a smaller hotel outside the suburbs with little competition, it can be difficult to earn back the RMS, while it can be interesting for large hotel chains and hotels with a lot of competition.
