NCL has just confirmed that "Pride of Aloha" will revert to "Norwegian Sky". The ship will commence three- and four-night cruises out of Miami in mid-July.
It'll wet dock in the Miami area over 4 weeks, that's a long time for "routine" maintenance.
I imagine a completely refurbished ship when it reenters service in mid-July.
NCL is also going to have a Kids Sail Free Promotion for just the Sky (fares free only, not the taxes and fuel surcharges) attempting to attract more passengers considering the relatively short booking time.
