Asks in the category of "I think they could do this if they wanted/enough people complained about it"
I wish they would go to the safety drill like all other cruise lines now which is done remotely instead of in person. Especially on a 3 night cruise, a meaningful amount of time is spent waiting for the drills, waiting for everyone to come to the drill, having to stand around for the drill, and waiting to get back to the ship to your room/deck party, etc.
Another change I would like is offer more varied nighttime adult entertainment - on our recent cruises the only nighttime dancing was the "silent parties"
I wish the pools (especially adult pools) were open later at night - other cruise lines keep them open later, but everything closes early on the pool deck on
DCL.
I also wish they would hold a "midnight buffet" (if not at midnight) on the night of Pirate Night
