I have been advised by Tegal Sari that in order to secure a booking they will not only require my Credit Card number but also the 3 digit authorization number on reverse if card, this is because I want to pay in Rupiah when I arrive and do not want to pay with c/card or bank transfer. I am not comfortable with providing this number. Can anyone please advise on what they have done in this circumstance? Any thoughts and suggestions would be much appreciated, cheers............Kris
