I've learned a long time ago, crew rumors are just that, rumors. I think
DCL made plenty of money on those two cruises compared to what they would pull in during that time, considering they were non-summer/non-holiday weeks. (I know I spent quite a bit more than we usually do on just about everything - merchandise, drinks, excursions.)
It may not have been as profitable for the serving teams because the # of people was down but that doesn't mean DCL fared the same way. I don't think they are going to be putting Hawaii on the schedule every year. But I wouldn't be surprised to find a couple of cruises on the 2015 schedule.
