Of the voyages they canceled, I'd be very interested in the percentage of people who rebooked for a different date. If they did that to us, we probably wouldn't rebook imminently as we plan our travel far in advance, mostly thanks to DVC.
Also think it's fascinating that they have operational/occupancy flexibility that normal hotels/cruises don't have. Hotels/cruises realistically can't shutdown like this.
Unlike a hotel, which has extremely variable check-in/check-outs from its guests, Starcruiser guests are neatly organized on the dates they 'voyage', so they can cleanly shut down for 1-3 days at a time when a hotel couldn't without impacting a larger number of booked nights. And unlike a cruise, Starcruiser probably has nearly zero cost for the days it's shutdown as it's not a high-maintenance ship with port fees, resident crew, etc.
Hypothetically, instead of staying open 100% of dates with an average of a 70% occupancy rate and gutting out the painfully slow days, they have the flexibility to be open 85% of dates with a slightly boosted average occupancy rate (say, 80%) and no painfully slow days.
Of course Disney would prefer to have overwhelming demand, but in the face of reduced demand they have an operational lever that they've never really had before. Yeah, they will have fewer heads in beds total by canceling voyages but also reduced operating costs and maybe it makes some CM scheduling easier by synchronizing days off (e.g., Jiko, Victoria & Albert's).
They're definitely going to get interesting-to-me data from this and I'd definitely geek out over it if it were ever available.
