I posted earlier about this because a some friends who just got back noticed a change . I'm hoping that someone who just got back or who will be staying at one of the monorail resorts soon will have some answers. We won't be there until August . My family gets a kick out of it. We even made sure we recorded it on video last December !
I answered on the other post--take heart folks, the phrase is still the same. The airport does give a warning that indicates the doors are about to close followed by "Please stand clear of the doors. . ."
