If the site in question is the one in your profile then it could the un-userfriendliness of the site.
Looking at it, there are too many things going on and seems extremely difficult to navigate in my opinion. Is there any need for that amount of ads? The ads look as if they will take you to another site, and your "Search Hotels" doesn't work "We are sorry, but we could not find hotel rooms fitting your search. Try selecting a different date or hotel type" is all I get no matter what dates I put in in Firefox..
This is only my opinion, but if I was looking for a holiday I probably would not use the site.
Sorry if I sound a bit harsh, but there is nothing more appealing than a clean, user-friendly, site to book a holiday through.
