Error Messages

What do I do in response to an error message?

From time to time users may be presented with an error message in the course of making a reservation. These may be caused by a temporary technical issue, a hotel policy constraint, or by some issue regarding customer input. Usually the issue is clearly identified by the message, for example Invalid Credit Card Number, but there are other cases where the message may be somewhat vague or ambiguous. Below are some examples of ambiguous messages, with explanations and suggested responses. Of course, please feel free to report any problems to us directly (


This can be caused by a temporary technical issue with the booking system, but is usually limited to the processing of a reservation for a particular hotel and is often an indication that no rooms are available that meet your requirements.

This message typically appears when you attempt to guarantee an advance-purchase or advance-deposit room with certain hotels. If you select a room without an advance-purchase or advance-deposit requirement you can avoid this error. While this may result in a modest increase in cost, avoiding the no-refund policy that typically accompanies advance purchase rates preserves greater flexibility for you and is something you should consider.


For some hotels, the Child parameter is not supported by their automated system. If you get this error simply count all guests as adults when doing your room search.
