It's not heavy-handed... it's about being prepared for every contingency.
Hospital facilities ready to take care of sick passengers?
Quarantine facilities ready to take care of exposed passengers?
Let's be serious here. How can you POSSIBLY restart cruises and not have arrangements in place to handle these situations in advance. In Disney's case, the quarantine situation is pretty easy because they already have tens of thousands of hotel rooms...and many aren't in use anyway due to the pandemic.
As far as hospital capacity goes, many local government set up temporary hospital facilities in convention centers and arenas last spring. Again, local governments that want to get cruising back in place can help put together these contingency plans.
I'm not sure how anybody could agree to a restart plan that didn't address these possibilities. Now, does Disney need to have 4000 empty hospital rooms ready? Clearly that's not necessary, but there needs to be some sort of plans in place to handle the possibility.
The only part that I think needs adjusting is the gangway issue. Science has made it pretty clear that "deep cleaning" isn't really necessary, so I think the cruise lines should push back on that part. But that's not enough to say the whole thing is onerous.
Several other countries/regions have restarted cruising without these arrangements, and after months of sailings and 400,000 passengers, there hasn't been a single instance where any of this backup stuff would have been helpful. Furthermore, if you have fully vaccinated cruises, and regular testing, there is a near-zero chance you would have a large outbreak on the ship.
Local governments aren't going to spend the money to have empty hospital capacity for cruise ships, which would be more than just tents. It would be equipment, supplies, and even stand-by medical personnel. And they are required to have this setup with
two different hospitals for each person. They also need to contract with emergency transport to be on standby and ready to transport passengers. It would be many many millions of dollars to have that ready for
each cruise line (they can't pool resources - they each must have separate agreements with hospitals). No government is going to pick up that bill.
Even if Disney has the excess rooms, where does that leave the majority of cruise lines? Do you know what it would cost to have 10K plus hotel rooms on reserve every day of the year? I don't think it is realistic for the large lines.
Let me ask you this - if it's not heavy handed, do you think cruise lines are walking away from millions in revenue just to stick it to the CDC? Of course not. They are internally evaluating if they can comply and deciding they can't, because either the revenue would not exceed the cost or compliance is simply unrealistic. It's may be both. I am really not sure what the point of this debate is, when the cruise line's actions says it all. If compliance was a viable path, at least one of the lines would be moving forward with it. They aren't going to walk away from millions in revenue to prove some moral point against the CDC.
I think ultimately it comes down to whether you think cruising should resume or not. If you think it should, there should be more realistic and obtainable precautionary measures. Putting in place measures that have effectively just continued the no-sail order isn't very helpful to the end goal. If you want to argue that sailing is simply too dangerous to do it in a manner that isn't cost-prohibitive, then that's another debate, and a position that I don't agree with. Not to mention that the CDC will simply be pushing Americans to fly to foreign ports to sail if they dig into this position.
