I stay almost exclusively in hostels when available and use sites such as hostelworld.com or hostelbookers.com to find hostels.
When looking for a hostel in Casablanca no hostels could be found on these sites, but an Hostelling International (HI) associated hostel does exist and can be booked through the HI site.
HI hostels in the US, UK, Germany and many other countries are listed on the hostel booking sites, why not the Moroccans?
More important is the question whether there are other countries that don't have their HI hostels listed? This would mean I always have to check the official HI site as well.
A list of such countries would be nice, does one exist?
