I meant to post this a while ago.
RCI recently revised their debarkation protocol. Now called "As You Depart", this program is similar to those already being done on Princess, NCL, and some other lines.
Specific lounges are designated for color codes. Light refreshments and entertainment provided. When the time comes for your color, a crew member will escort your group to the gangway. You can also remain in your cabin up until the time you were told to be at your designated lounge. Announcements are also being limited to inside the cabins and in the designated lounges. Thus, if you don't follow along and be where you are supposed to be, you may miss important information or even miss your call to leave.
Self-debarkation is still available where allowed, and suite guests and higher level C&A members will have private lounges and priority departure.
