I've written twice before and been told it was fine. I just wrote again a few days ago, and haven't heard back. You can get various opinions on this by doign a search, but you are better off writing to guest services and asking for yourself, since it appears there are many opinions on this. Another gal just posted a note she got from guest services, that didn't agree with what my last note said, which was why I forwarded that note to guest services and asked what's up with this question, that we get different answers. I'll be posting the answer I get, if I ever get it.
