I had emailed "sunnysafaris" for the safari in tanzania,
as for making sure the resevarion, they emailed as below:
"We kindlyask you to send us 50% deposit or your credit card details for security for our reservations and shall go
aheand and confirm your bookings accordingly with us. We can also accept your credit card details for security for
our reservations and on your arrival here in Arusha at our office you can make the full payments with Cash USD,
travellers cheques or with visa/master cards."
is that ok to send them the deposit or the credit card details?
sorry for my english.
