According to Marc Stein, NBA teams are likely going to be limited to "bring (roughly) 35 players/coaches/staff into a 'campus' environment if the 2019-20 season…resumes in July."
The continuation of the season is looking increasingly likely to happen in July. Those travel parties of 35, notably, have not mentioned the players' families (or anybody's family members, for that matter). There will undoubtedly be further developments as the situation materializes.
