Princess Cruises and other lines are implementing a fleet wide mobile-app driven experience that uses Bluetooth Low Energy beacons in concert with a mobile app to enable all of the commerce that takes place on their cruises. Everything from unlocking your cabin door, to ordering room service, scheduling spa services or shore excursions and paying for a beer at one of their bars - it’s all driven by the app.
I was on basically the maiden voyage when they rolled all this stuff out, and it was pretty rough. The app, in particular had the vibe of being slapped together by offshore contractors. That said, it worked well enough but I would not be at all surprised that cruise lines want to continue investing in this infrastructure, especially given that it enables social distancing by default.
I can’t imagine it would be fun to work for a company that doesn’t understand tech outside the context of high priced contractors though, just from a culture perspective. Hospitality companies in general are very old-school in their approach to workers.
