We were just on a DCL cruise a few weeks ago, and think it's worth every penny. A few things to remember. At the present time, you do have to wear masks anytime you are indoors unless eating or drinking. No masks required outside at all. No one knows when this restriction will be lifted, but should be gone by the time your cruise comes up. Next. Every person over the age of 12 has to be fully vaccinated by the date of the cruise, and every single person, regardless of vaccination status, has to take a COVID test at the port, and if even one person in your sailing party pops positive, your entire party will not be allowed to sail. In addition, all children under the age of 12 have to have a negative test 3-10 days prior to sailing as well. You will have to pay for this test, but Disney is paying for the test at the port. Again, since your cruise is not until Dec 2022 or so, it's is entirely possible that all of these restrictions will be totally gone.
The CMs on the ship are no less than spectacular. It is first class service all the way everywhere, and the crew looks happy to be there to make your cruise an awesome experience. All the CMs we interacted with were smiling, and all were friendly and helpful. They are really glad to be cruising again and to welcome guests back on board the ship.
I kinda disagree with
@Phonedave about the alcohol being an obvious money grab. Yes, the alcohol is not included, but I think that the prices were not out of line with what you got. We never saw one person that had indulged too much in the good stuff. If you drink wine, you can bring 2 bottles per person onto the ship. We enjoy adult beverages, and even went to a mixology class and different tastings. We thought they were worth every penny.
Our kids are grown and married (we took our youngest son and his wife on the cruise), so we haven't experienced the kids areas, but everything we've read say that they are the best in the cruise industry. Someone with younger kids can answer that better than I.
So long read, but final note - if you choose DCL, you will not be disappointed!! Oh, and I am NOT a CM or Disney employee. This is totally unbiased and my opinion.
