So the few days hop over to dive the sister islands still isn't going to be an option unless it's booked within 90 days if I read that correctly. Shame.
In this boom time right now, I see several condo rentals on Grand Cayman also going to Sat-Sat, in an effort to further squeeze a little more paid occupancy out of the situation. I, personally, won't follow that on my rental because the idea of people being able to come and dive for a long weekend is one that I want to be able to continue to offer. If we get a couple of days free in high season, then that is just an opportunity for our maintenance folks to come in and do preventative maintenance on things.
I also understand the logistics of getting to and from the island. The consequences are a shame, though.
I don't think so, because if they are planning to allow folks to book 10+ days and that will create some long weekends that they will be eager to book as soon as possible.
It seems like they are trying to figure it all out, but it's great that they are also trying to be open and responsive to guest requests while still attempting to address the flight issues that have been so problematic in the past. Maybe just give it a little time while things are getting sorted out and then enquire - it can't hurt to ask.
And as mentioned there are other dive resorts and condos on Little Cayman (but probably not during the August through October shutdown) and the Brac Scuba Shack offers diving and accommodation packages, see the link below:
