I have made a booking at a hotel in an East Asian country for the new years period.
The booking was done through a 3rd party website. The payment will be fulfilled on the first day of arrival through the 3rd party website.
Last week I got a mail that seems to be from the hotel (mentioning my full name and everything) that I have the possibility to book a table for new years eve at their restaurant, to which I replied positively.
They replied though that in order to book a table at the restaurant, they require me to send them a credit card authorization form filled with my bank and other personal info (credit card number, a copy of passport etc). I am a bit reluctant to send all these personal info through email. It also seems weird to me that I should print a PDF, write my personal info, scan my passport etc and then send it via insecure email, all for a simple restaurant reservation.
So my question is, is this normal practice and I'm just paranoid?
Just to mention that the hotel is from a really big international chain and not some small family resort or anything.
