We have gotten most of our rooms free for quite a while now by receiving room offers in the mail. Well, sometimes we have to pay for a weekend night. For our upcoming trip in October, our room is being comped by a host. Is it common to not be given a reservation #? That makes me a little uneasy, but if that's how it's done so be it. Just do not want to get there and they say "who the heck are you?"
