FYI, if you do get one, the pin code is not "in your face" i.e. easily identified. The email won't say "HERE'S YOUR PIN CODE!!!" Usually it's at the bottom of the email, it's usually a 12-digit or 16-digit number, somewhere near the telephone number to call for a reservation, and there will be dates when it's applicable. I say this because some people have missed the code altogether.
