Right now, there are some deals for upcoming cruises (after September 15, 2020). However, they super cheap. After all, there is a minimum needed for the cruise lines to pay their employees, buy fuel and food, etc.
The cruise lines, though, have said that these lower rates will not last. As bookings continue to rise, the prices will go up. This is how it normally works.
So, if you are looking for that special deal, now is the time to purchase.
If you don’t care about the type of stateroom you get, what itinerary you get, and you can cruise last minute, you can HOPE for a real deal closer to the sailing date. There are never any guarantees about this, though. So, if there is that special cruise you wanted to take, and you care about your stateroom, you can’t wait.
