In this case, I would choose HAL. I have done transAtlantics on HAL, Celebrity, and Carnival. Also longer cruises on all. I like a nice afternoon nap, but on HAL and Celebrity, I had trouble fitting it in due to all the interesting activities, including great enrichment lectures. my Carnival TA on Dream was by far the least expensive, but with a lot of sea days there was not one speaker. Managed to get the naps in on that one. I had several others booked that were Covid cancelled. EM
