I think what DJ Travel was saying was that when he selects discounts (M11 or just weekend specials) they do not allow him to select preferences.

I too have seen this. (ie. You may only select 1 preference on the preference screen) The problem is that on that screen I generally have 4(King, Non Smoking, Rollaway, High Floor) I noted a refrigerator when I did the "NEW" Preference profile, so it adds that.

I have however found that if I don't touch the page (to add the rollaway), it normally will Gurantee the King, Non. I then just call in and Gold/Plat Line adds that and the Upgrade Requested Tag.
