To be fair we chose HAL for this trip simply because of the small travel window we had available and a last minute decision they were the only line that would work. I don't think this is probably a compatible line for our travel type.
Stateroom - wonderful. Almost the only inside cabin on that deck but no one on either side of us. So quiet, comfy bed and larger than expected.
Stateroom attendants - did a fantastic job. Fast, thorough and so friendly. Earned every penny of the extra gratuity we left for the both of them.
