What confirmation do you get when booking a Disneyland hotel with points?

It's been a (long) while since I did this but I just booked Paradise Pier for one night as a wedding present for a friend. I got a given a 5 letter confirmation 'number'. No email confirmation just that. I just wanted to be sure it was right as I'm doing it for someone else and I don't want them to have issues when they get there!
