It's far far far less of a risk with
DCL, they have very large Corporate structure behind them that while it is multi layered and vast, it more than can support losses that the cruise line might encounter for a while before they would have to consider any thing close to bankruptcy or completely folding. With 3 ships (I know everyone's speculating that they will cancel the 2 remaining to be built or scrap all 3) coming online in the future, and also that they're planning significant changes for the existing fleet (re-configurations to accommodate for Covid-19 safety protocols and social distancing) during the shut down indicates that DCL is in it for the long haul and will come back when they can. So considering this avenue for DCL just isn't practical or logical.
