This reminds me of an interview Piers Morgan did back in 2008-2009 in a show about Las Vegas. Leading up to the Housing Crisis, Vegas was going along nicely but reasonably, then during the year and a half of the worst of the recession, Piers was interviewing the owner of the Planet Hollywood resort and asking how they were handling the worst downturn in years. The owner says we are giving away rooms free basically to get people in to spend money.
Piers then asks him what happens when the economy improves and demand resumes, and the owner says flatly, I will rip their jugular's out, meaning you will pay through the nose, which is kinda what happened several year later as the recession waned.
Currently RCL is going for our Jugular's, until we sequel and demand lightens up, but I think they feel they also have a great product with their ships compared to other lines and figure when the rides over they can lower the prices back some and demand by people who like their ships will remain or come back.
