Royal Caribbean cruise line is looking for volunteers to help their ships test new coronavirus protocols. The upside: the cruise is free. The downside: you could catch COVID. The cruise line has been working on training their crews in new health and safety protocols and conducting a number of trial sailings to stress-test those protocols in real-world conditions. Part of the test is that the ships must evaluate their ability to mitigate the risk of the virus while at sea. Those who volunteer will get the chance to cruise for free, but be warned it will not feel like a standard cruise vacation. Royal Caribbean is searching for volunteers for cruises beginning in 2021. Here’s the complete story from Travel & Leisure.
