Yeah, no, both to making exceptions to the law and to me taking any cruise any time in the near future. Assuming this is before a vaccine or other elimination of COVID-19, I'd suggest everyone who disembarks such a cruise be quarantined in isolated tents at the port (at their expense) for 14 days before being allowed to proceed home.
The cruise lines messed up really badly (forcing people to board or no refund for a full month and a half after the Diamond Princess, then crying about cities not wanting to take in ships with mass spread). There are many many other businesses and activities that can and should be reopened well before cruising is allowed.
