Similar to this subject, Marriott has an option on the preference pages for a few things, such as a refrigerator in the room. I have it checked, but only get one about half the time. Of the times that I did not get one, only one time has the clerk appologized that they didn't have one available. I understand that it is not guarenteed, but they could at least acknowledge that I requested it and it is not available instead of just ignoring the subject.
It is not a big deal to me unless I am traveling with my family and want to keep left overs for the kids, but it appears that most hotels just ignore the request made by a Platnimum member on their website. If they are going to do that, why do they have the option?
