Certainly seems hit or miss with different interpretations of what can be done. I called a few weeks ago in anticipation of hitting Diamond yesterday. The person I spoke with was well informed, advised how to work with my PCC to best book OV’s on a BTB to be upgraded today. She confirmed that we could identify open cabins and/or preferred location and that she’d have no trouble executing that, and probable that we could get same cabin for both legs. I called today 3 times, 3 different people, the first 2 with literally NO knowledge of what I was talking about. #1 transferred me to our PCC…who was understandably annoyed. #2 was absolutely obnoxious, said that the published number was wrong, that it wasn't handled by the Latitudes “Pre-Cruise Consultant” as that line is answered, and tried to transfer me to the unanswered “Resolution Desk”. I simply dialed the 3rd time and reached a very knowledgeable and helpful person who equaled the person from a few weeks ago in knowledge, creativity, and service. Lesson learned and worth sharing: do your research ahead. Identify open cabins in your preferred location. If the person who answers the dedicated line has no idea or gives you less than satisfactory answers, MOVE ON! Hang up, keep calling until you get a good one. No confirmation yet, but he was confident that with the information I gave him and he included in request, that we will get what we requested. OA to BA, single cabin for both legs, on either of 2 floors in the general area desired. 🤞
