According to the Walt Disney World website, operating hours for bus service between Walt Disney World resort hotels and Disney Springs will be extended. Below is the announcement.

Beginning November 29, 2020, bus service between Disney Resort hotels and Disney Springs will be available during Disney Springs operating hours—and will end one hour after closing.

Disney Springs will be open until as late as 11:00 PM some days through the winter holidays, which means buses will run from 10:00 AM until midnight.

Bus service between hotels and theme parks begins 45 minutes before a park opens and ends one hour after closing.
