I am willing to bet a drink on that RC would like to sail many cruises / guests through the Panama Canal, remember that they have built a completely new size of ships (Quantum Class) suitable for the expansion of Panama Canal .... I think the waiting safely with publication of timetable / cruises since the Panama Canal opening has already been delayed for two years and currently missing 10% from being finished.
At present, the open time of the new Panama Canal set to the early summer 2016th. I am happy that I can't buy a cruise of RC that might not be possible. I am very hopeful to see how I can sail through the Panama Canal with RC.
I hope most of all to be able to sail something like the "New York" to "Alaska" through the Panama Canal.
