If CCL, continues to go overboard( no pun intended) on more than mandated or reasonable safety...then it will not survive as a company. You cannot possibly cover every issue....what about nail fungus checks, could catch it in the locker rooms, on and on. Look CDC has released the burden, now is the time to remove all the obstacles for cruisers, make it EASY ...just ask for a vaccination proof, and stop. Endless , expensive testing weeds out only a minimal amount of cruisers, so why insist on the Pre cruise Barricade. This alone is particularly huge problem.
