Obviously, this is not an official position from Disney, but I just did a quick check on cruises on the Magic and Wonder for the next couple of months. Doing a random sample I could not find a cruise where you could select a deck 2 cabin in February, March, or early April. But, in late April, May, and June they are available. The earlier cruises have some GT cabins on deck 2, but with those Disney can move you. This leads me to think that
DCL feels more confident at this time that late spring and summer cruises will not need so much quarantine space. Hopefully, there will not be any more variants to change that.
