It’s not just that they took the perk away, but they have made it so that you are essentially punished unless you take their expensive transportation. Like I said, people who are have never cruised before are getting on right when boarding begins while people who have cruised 20 times has to stand outside the terminal for an hour. And then DCL did absolutely nothing to replace the perk.
Guests who are not arriving on Disney transportation don't have to stand outside the terminal unless they arrive well before their port arrival time (which they can avoid, since they are handling their own transportation).
Guests who are arriving on Disney transportation from the parks don't have control over when they arrive, so if they had to select a port arrival time and earlier times were taken, they would need to wait outside the terminal.
It might be possible for DCL to assign people with higher
Castaway Club status who are using Disney transportation to earlier boarding groups. However, that would mean people with lower status would be in later boarding groups, resulting in more people in the terminal at an given time. It appears that the goal of the current port arrival time/boarding group process is to minimize the number of people in the terminal.
I agree that it was great when as a Platinum Castaway Club member I could board whenever I wanted after boarding began. However, waiting 15-20 minutes after boarding begins to board the ship hasn't been that bad -- on my 2 cruises this year, I was onboard before the sit-down restaurant even opened for lunch, well before the Dining Changes area opened. I'd rather stay seated for a few minutes than fight dozens of other Platinum guests to line up at once.
also lost abilty to book on first day of new iteneraies, now platinum can book 2nd day, can make a diff in cabin selection & price
This wasn't really a loss -- Platinum can still book before Gold, Silver, and new cruisers, as they could a few years ago. It's just that Pearl (which is a small number of guests on most cruises) can now book before Platinum. Yes, it is possible that a Platinum person can't get the specific cabin they want because it was taken by a Pearl booking, but there are many cabins available. It's also possible that on a small number of itineraries there could be enough Pearl bookings to result in a price hike before Platinum can book, but I think that's unlikely.
