With the early park closing times... We sometimes did a last ride at a premium attraction near park close in order to extend our park time. For instance, we did Mickey Minnie Runaway Railroad at just a few minutes before park close, and instead of 8pm, we were leaving the park about 8:45. You could also linger at the park for a bit to shop or shop at your hotel or DS.
I believe there are also certain in park restaurants that will let you to continue to dine past park hrs. But for us, we were more considering between DS, eating at our hotel or surrounding hotels on the Boardwalk, or Uber Eats.
Fantasia putt putt was open (but not WinterSummerland). I think AMC is now showing films, and Splitville bowling is open at DS. You could go for a swim, although I think most Disney hotel pools are from 9-9? At the Swan, ours closed at like 10pm (one rep told me midnight and another said 10), and I think our Pop Cent. pools were 9pm.
My wife was content most nights (being back at our room earlier) with the food network on or a movie, laying in bed with a book, while I tried to get our stuff/snacks organized for the next day.
