The main concern and important point of view is that the system gives the opportunity without any effort to commute their travel products - co-operators' products (hotels, agencies, activities, rental cars and motors, etc) in all the users or partners (that use the system ) webpages and all B2B agents. Intercommunication is exactly the word that defines the product !
B2C is working usually form hoteliers web page.
Also B2C may be working from association or cluster of hoteliers webpage and in that way to have an important tool to decrease expenses for promotion and marketing !
The more you are - The most benefits you have !
