Some hostel booking sites require you to give them the lowest price that is advertised anywhere. Some even require hostels to give them the same rate that is on their websites.
For example, I've heard that hostels (and hotels) are forced by booking.com to give them the lowest rate that must be as low as the rate on all the other booking websites, and even as low as on the hostel's own website. When multiple booking sites do this, it seems that hostels lose control of their own pricing.
I'm wondering if we could compile a list of all the booking sites that require this. Do Hostelworld and Hostelbookers require this in their contracts?
Also, what do you think about the situation?
