Rate details can be negotiated that includes just about anything, plus or minus. Some convention rates may include a lower rate for not including MR benefits just like I've seen some corporate rates that include local transportation to/from company facilities. As long as the terms are properly disclosed as agreed upon then perfectly acceptable. And it looks like this was disclosed. Failure to read the rate details does not entitle the guest to the benefits regardless of status. Just like it's wise to compare rate details between AAA, AARP, Weekend, etc. rates to see which one provides the desired perks, it applies here too. Another gotcha with rate details is they can change without warning! Typically the systems use an index code to refer to the details. So when you book, let's say, a AAA rate, your booking record may use a code of X3 that is not visible to the user that points to the full text of the code. A future edit of that text will be what shows up if you go online to look at your reservation. This is why it is important to keep a copy of your confirmation (email or screen shot) until after the stay posts. Some have been caught by such changes and the online system only showed the latest revision.
