It seems they still have some rooms blocked off for quarantine. So if not at full capacity, close to it. My guess is somewhere in the 90% range should be a "full" ship at this point.
Keep in mind that there are different ways to determine "full capacity" -- # of staterooms booked vs # of passengers, also maximums allowed by age group (0-2, 3-12, 11-14, 15-17). A "full" ship may not have any rooms available but doesn't have the max number of passengers it could potentially hold, which was not uncommon pre-covid.
