LOL, youtube! In all the years I've participated in Cruise Critic, I've only seen a few mentions of youtube. I did try watching a couple that were recommended, and realized they were not a good source of information, and were not very interesting, either. Just one person's take, and generally tainted by their own likes, dislikes, and preconceptions.
One of the nice things about CC is that information (or opinions) is up to date, and can be modified/debated constantly, just like the comments above on the friendliness, or otherwise, of crew. And then there is actual news, such as vaccine requirements, that can be modified as things change. Keep reading CC!
