well what other basis would you like me to comment on other than my own ACTUAL experiences and from talking to numerous hotel managers who have also confirmed this with me, I dont quite get your point, if you dont agree fine, I couldn't care less, just my view, take it or leave it, up to you. That IS how and why many hotels avail of using the booking the sites - to their "mutual" benefit, it's not like that's an industry secret or anything ......you dont know this ?
