so far Agoda has served me well ..the good thing about it is the deal ...but do compare with few other more la ..
I have book few times with Agoda , trip to HK,Macao,Bkk,Indo and others.
Good,fast,reliable,excellent customer service and fast reply ..highly recomended ..but again do compare before you decide ..

Other webbies that I used :
www.asiarooms.com
www.marimari.com
www.directrooms.com

i am sure mr google,mr bing and others will give you even ,more ..just type your hotel name in their search column ...then you have thousands of deal ...enjoy browsing
