Okay, so here is the trip report...
Final decision - Orange UKPK.... I guess I always knew it would be but it was nice to get validation on my choice.
Flying - tucked it in a zipped compartment in the checked suitcase. No issues either way (expected).
Initial boarding - same place. It seemed to work for the plane so.... They did pull aside a suitcase I'd accidently left a bottle of vodka and a bottle of rum in

:o

. Strategically, I'd put the UKPK in a different bag.... :D (both were expected). Funny story there for some other time.
Port disembarking - just wore it RFP. No issues as you really don't go through any screening (expected).
Port embarking - Placed the UKPK in the camera bag in the sleeve with the telephoto lens. Only two ports had xray scanners, the other two had some kind of odd random visual search. They kinda glanced at everything (placed in the same kind of trays they use for xray scanning) and if something caught their attention, they looked further. For example, they were very interested in the wooden wall hanging we bought on Maui... A fish and turtle kind of thing... :confused: but never once opened the camera bag.
Would they have cared if I'd just put it in the tray and sent it through xray/screening? Dunno. Would they have found it were it still in my pocket? Definitely, every time. Would they have cared? Dunno, but my guess would be yes, some. They got very agitated at ANYTHING that set off the metal detectors...
I can't say this is foolproof, just that it worked for me on this trip... I was able to carry 100% of the time on the ship and 100% of the time off the ship. I was very happy it all worked out.
Was I glad I had it? Of course. Dozens of open this and trim that moments like we all have every day but there was one outstanding moment. We were taking a tour through a botanical garden and the guide stopped and picked a mango from the tree. She gave it to Arlene. My impression was she wanted her to try it and 'report' to the rest of the tour... Instead, Arlene handed it to me and and I made slices for everyone to try. It was the best mango I've ever tried. Everyone loved it and was thrilled they got to try it too. The UKPK was a hero!
Well, that's the report. Thanks to all of you for thoughts and input.
I wish you equal fortune in any travels you undertake.
