Was recently on the Joy and it had probably 75% or more capacity. While it didn't really feel crowded, we stayed away from the small venues (which are enclosed and got very crowded). Pool area was crowded too. We tried to stay away from cramming Into elevators and I would have felt more comfortable if the staff had been wearing masks. We did at certain times; we still came home with Covid, as did lots of other passengers. Since we tested negative at boarding, we got it either onboard or in one of the Canadian ports. Not complaining, we chose to cruise, but the two previous post-covid cruises we took which were much less crowded, posed no problem, to us at least. Breakaway is a large ship (we've been on that) but have always been able to find less crowded areas. Be prepared that you WILL be mingling with a lot of other folks..
