Disney World waited a full month to reopen after both Universal and Sea World had reopened. They did not jump in and reopen as soon as the law allowed. In the context of theme parks in Florida, they were the slow and cautious ones. They maintained their safety-first image by waiting to reopen and by maintaining the strictest protocols upon reopening. The opinion of a British editorial board on Florida's reopening is irrelevant to that (not to mention that the BBC is currently under investigation for unethical behavior).
Likewise, I have no doubt that
DCL will hang back and watch the other cruise lines resume sailings before they do the same. Whenever cruising resumes, there will undoubtedly be some opinion pieces written claiming that it's too soon. But that doesn't change the fact that DCL is undoubtedly going to err on the side of caution and watch other lines sail for at least a month or two before they do the same.
