I don't see Disney giving that access for "free" or included in the price when things like the VIP tours don't include a ticket either. Heck, the "World of Dreams" tour cost $12,000 and still doesn't include a park ticket.
They could have a line charge on the bill for a ticket per person or something though. But, I imagine a lot of people will stay there for 2 days, then transfer to another resort for the rest of their vacation. If you have a 6 day ticket, it would suck to have to pay a full day price for one day when you are going to purchase a cheaper per day ticket for the length of your stay. However they do it remains to be seen, I just do not see HS access during regular park hours being included. As they say "that's not Disney".
The use case is different between the tours and the Starcruiser though. In a way that directly impacts ticket management.
With any of the tours, it's an add on experience that can happen at any time. Go for 1 day only and only do a tour. Do a tour on the first day of a longer trip. Do a tour on the last day of a longer trip. Do a tour on a random day in the middle of a trip. Plus, a tour isn't an entire day thing. Except for the first one, for all the rest people are already buying longer duration tickets. They would overlap with the same time period. Trying to manage that you bought a 5 day ticket, but on day 3 of 6 you're going into a park on a tour and not using that ticket would be a huge hassle. I have never done a "resort day" in the middle of a trip, it's that even something you can still do with the new variable ticket pricing?
While it's possible to book Starcruiser in the middle of a stay, that's not really what they're expecting, based on the pitch. It'll most often be at the start or end of a trip. Exactly the same way a split parks and Disney Cruise Line trip works. Using that model, the first or last day may overlap with the rest of a trip using the parks, but the middle day is clearly targeted as a cruise day. My guess is the middle day will include park entrance to DHS. It'll obviously be easiest to travel on the cruise shuttle, but I doubt they restrict access at the front gate if you end up there for some reason. Even with a dedicated entrance, they'll have to have tap styles there. If only to validate you're a cruiser before letting you board the shuttle back.
The embark and disembark days are more interesting. Until we have details on times and expectations, it's harder to tell. If we assume the first day starts late enough, and includes onboard activities, then there's no reason for them to include a ticket for that day. On an end trip cruise, you would need your original ticket to include time for morning parks. If the last day ends early enough, you're kicked to the curb nicely. On a start of trip cruise, you would need your resort ticket to cover afternoon parks. If those are travel days, they'll just assume you're on your own to skip the parks or add a 1 day ticket. If the times are different, arrive early and check out late (which means they need an empty night between cruises), all of these thoughts are different.
Much like Castaway Cay is included in a real cruise, that would be my expectation for the middle day including DHS.
