Good topic. Thanks for the link to the article in the Guardian.
I would be very reluctant to go on any long distance air travel for vacation without some sort of immunity, whether acquired naturally or through vaccine, or without the virus substantially disappearing like SARS/MERS. As for management of the resort, LOB, meals, diving boats etc, I'd rather not go if the "vacation experience/atmosphere" is undermined. Meaning that if I'm not comfortable mingling with a limited amount of strangers, given that they too have been travelling through airport and airplanes, then why bother going on the vacation?
What measures would people want? For example, if a tourist or resort worker sneezes or is feeling unwell, should we be wanting to make that person quarantine? Are test kits suddenly going to be available and reliable in remote, hot, humid conditions? Setting up one's own gear is one thing, but are we going to want surfaces of the boats to be disinfected? At home, we do what we have to do, we take the precautions we have to take, because we have to go about our daily lives. But I would not want a vacation under those circumstances.
That's my thinking in the short run, based on what we know at present. But I'm open to ideas from others. And if this continues without a good solution, in the long run, I may have to change my mind, and be willing to consider a vacation under changed circumstances.
