The lowest Concierge cabin on DCL, the balcony, is where you really get little return on your investment. Not only is it very similar to a non-Concierge balcony in size, you do not get a fold-out double sofa sleeper instead of the sofa-back twin + upper berth.
I wonder if they are also low on the priority list for a cabana at
Castaway Cay? That opportunity to pay more money seems to be the sole domain of Concierge now.
@John VN ‘s post points out, there are definitely ways to get a more exclusive, all-included Concierge experience on other lines for exceptionally less than Disney.
I have cruised in DCL concierge a few times in the past (without the steep current upcharge), but could not imagine doing so now. I didn’t even appreciate it for little money. I also don’t like being fawned over. But I appreciate the short Platinum check-in line at the port. And access to airport lounges (back in the day when we could still get in).
