Not likely things changed from when you started a duplicate thread a few hours ago.
I asked the hotel manager this exact question last month on Summit. Was told staffing was the main issue. Not only to set up the event, but send out the invitations.
If you want a M&G simply set up a place and time on Cruise Critic. Not hard. Better than Princess which provides nothing. You coordinate with them and they provide a time and location.
On our last cruise on Celebrity there was a slot pull, bar crawl and other events organized by CC members.
