Pre-shutdown usually about the 1-2 week mark they disappear from the site but you could call and book until like 48-72 hrs in advance Assuming space was available
They also won’t show up sometimes because of the number of passengers and or age of the passengers. They have to allocate rooms and occupancy based on the muster stations and their capacity and also the kids clubs capacities.
Typically… cruises were taken offline 3 days prior to sailing, though could still be booked by phone. They also won’t show online if fully booked. Occasionally they pop off and then back if DCL is working on assigning GTY staterooms or other behind-the-scenes maintenance.
Over the past year+ it has tended to be a sign they were getting ready for cancellations. But I can see the August cruises so I think the OP must have a filter that is blocking the Dream cruises from showing.
