I cancelled their bookings few months back for a hotel in Shenzhen. Ridiculous, asking me to forward all my personal particulars like photo copies of my credit card, passport and etc.
Booked 2 rooms at KL cititel mid valley hotel on 20 Dec 2008 and received 3 emails within 5 mins after booking. first was reward point follow by credit card booking confirmation and lastly hotel voucher. very efficient
