The travel restrictions make it a non-starter.
That being said, if they could manage some sort of an exemption I could see them doing something like:
- Each player/coach gets something like 4-5 tickets for family (so something like 150 people total)
- 2-3 families per section in the lower bowl
- Something like 6 or 8 rows between family groups
- Do this for Games 4-7, so basically anywhere from 1 day to 1 week
- Families stay in the hotel bubble space previously occupied by eliminated teams
- Obviously, same bubble procedures that always apply
With a very minimal level of logistics about entering and exiting their areas, that really should be completely safe. And it would make a really cool dynamic for the presentation of the game. But it all depends on getting travel exemptions, which is not something they can do with the save of a hand.
