It has been years since I sailed HAL and there are several reasons I have stayed away.
The crowd was uniformly older than any other line in my experiece. HAL has long had the reputation of catering to the more senior crowd.
The sports/athletic options were fairly limited. I am very active and like to have lots of options for exercise.
The food was a bit bland for my taste. I prefer to have a wider variety of more unusual choices.
The nightlife was pretty sedate and by midnight it was pretty much all over.
The Indonesian crew was polite and efficient but I prefer the more outgoing staffs of other lines.
For me, Celebrity has great food, high quality service, very nice cabins and beautiful ships. But it is also too sedate for my taste in a Caribbean cruise. I would cruise Celebrity in the Med but tend to stick to RCI here.
