Discounters cannot undercut some corporate rates, and therefore tend to position themselves toward other types of travelers. This includes leisure travelers, as well as entrepreneurs and those who are self-employed and working out of a home office. Once you decide to book a reservation with a discounter, be sure to check the confirmation, payment and cancellation policies. Services reserve the room in your name and then give you a confirmation number. That way you know that you are confirmed in the hotel's own records, not just in the records of a middleman.
Services have important variations in their payment policies.
This can create a crediting hassle if you need to cancel or make any travel changes. Cancellation rules tend to be unique to each service. The best policy we found was with Quikbook, which won't charge any penalty if you notify them at least three days prior to your stay or contact the hotel 24 hours prior to your scheduled date. The answer to that question may lie in the structuring of the services. In order to not jeopardize the deals they have with hotels, many services agree to avoid stepping on the toes of the hotel's regular market.
